Well, it yields a mix-grit edge. There have been stones with mixed grits for quite a while (I have one myself - Gesshin Synthetic Natural) just the target audience was more the kitchen knife crowd. Plus natural sharpening stones are all mixed grit by nature. But this is indeed pushing this concept even further and also opens up more possibilities.
Hey guys, this is Gabe - I am commenting from a brand new UA-cam Channel launched to explore this possibility. I’m going to shoot a simple tutorial on my method - to be released this weekend. I’m hoping that it catches like wildfire from there and we can all push the limits of the toothy-polished dual-grit edge! I’ll have Pete link my video, stay tuned.
In Russia so called Gabe edge is known as Gypsy edge(I don't know why it is called Gypsy) and usually it was used to make crppy steel cut aggressively. These days, with the widespread use of high-vanadium or high-chromium steels, such sharpening method is no longer necessary.

On the 6000 grit side does he go through the progression untill he gets to 6000 also do the arows dictate sharpening direction. I need to know. "Look of despair"
Tried this technique out on an old Henkel knife with a very dull edge (unknown stainless steel) and a very dull Leatherman blade, just using a Worksharp field sharpener at the preset 20 degree angle. I did about 10 strokes on the coarsest plate, then did the other side with 10 strokes on the smooth ceramic. Stropped both sides equally. Both edges were able to slice free held paper towel easily, with less than 2 minutes of time investment. I asked a friend, untrained in sharpening, to try it on one of his gas station quality folders. Same results. This really seems to work, and doesn't take much expertise. I imagine if you alternate "rough" sides every sharpening, your bevels will stay fairly equal. Anyway, while I love super steels, and have many of them, I tried this method on mediocre to terrible steel and it gave great results.

I think Sal and Eric Glesser would contend that this mimics the advantages of a serrated edge, just on a very small scale. The 250-grit side is like the side that would have the serrations ground in.
Just wait until people start putting tiny "microscopic serrations" on their knife edge. I think that this knife sharpening can be taken WAY out of context & can be looked at WAY too deeply. And I'm a knife nerd, so that says a alot. Technically you have "ruined" or "changed" the geometry of your edge on a micro level with the very first cut after sharpening.
I Think this kind of concept for sharpening is one of the best.. Japanese knife makers did some similar sharpening on kitchen knives and they stay bloody sharp for long time.
I do knife snarpening on the side. Maybe 20 a week. Not a ton but I’ve done over a thousand. Mostly high end kitchen knives usually to razor sharp. But also every other type. I own half a dozen systems, trying out before I got great at stones, the best system for every day man is the work sharp guided sharpener and get the extra plates/strop plate. It’s like $35 or so. I’ve done hundreds of Knives on that thing and don’t need any replacements. It’s brilliant. I’ve got their expensive ken onion work sharp pro and rarely use it. Only if reshaping a knife. I will go back to this little plate sharpener. I wish they’d pay me for the plugs I give them. Stropping is the most underrated or under utilized thing for sharpening. I just made a dozen 8” x 3” strops using maple, veg tanned full grain leather.
I agree about the stropping. I'm a fanatic about it. I strop my knife at the end of the day, and I can go a crazy long time before I have to put steel to stones.
@@konnan216 I agree that the precision edge is a great system...but as of now the guided sharpener has a better grit progression...but all in it's nearly double the cost.
I wonder if the direction of the coarse grit vs fine grit (which one is angled toward the tip) has any meaningful difference for different kinds of cutting tasks.
I really want to hear a LOT more about this sharpening method. First step will be to learn it yourself, so you can 1) repeat a test of the claims, and 2) DEMONSTRATE the technique so we can sharpen this way too.
Two things come to mind here. 1. It’s possible it makes a difference right handed vs left handed. I know when I paper test often the edge is sharper on one side, depending on which side I end with on the strop (being lazy). 2. I find that different sharpeners, stones, systems etc work different for different blades and steels. I can get better results on one system with one knife but struggle with another for example. I dunno. I leave it at if it cuts it cuts.
I'm testing this now on my CPM3V bush knife and my S30V EDC user. I'm using 380 and 600 diamonds and 10000 stroping compound. So far..? Wow!! Thanks for coming back!
I think the reason this works as well as it does is that it sort of duplicates a "micro" version of a good serrated edge. Scallops on one side and flat to the edge on the other, like the classic "spyderedge" on a Spyderco.

I'd be curious if he'd let you KME them and test them again just for kicks and see how they do. Just thinking compare exact knives sharpened both ways.
One difficulty with this method on a KME would be getting the sides of the edge even with two stones that differ vastly in their speed of removing steel, would almost need to start with an asymmetrical edge, or use a loupe or something.

There's obviously a lot of variables here, but your highest number on M4 steel 700 passes on a toothy finish. This would represent a roughly 40% increase over that score.

Well, the only way to find out is to try it yourself. This is Gabe, here is a short tutorial on how I sharpened the knives here, it's super easy to replicate, and you could test it any way you want: ua-cam.com/video/FruwVRSmhWA/v-deo.html
I'm going to give this method a try. The knives I carry stay sharp for a very long time. (K390, Maxamet, ZDP189) It is super hard to notice a bump in performance. I really appreciate the effort to test and measure the results...
I am going to try this out! I am amazed that this has not been tried before but it makes sense. My next sharpening task is going to get this edge! Very cool that Gabe did this and sent it to you and you tested it! Thanks so much!
I would love, love, LOVE to see what the edge looked like when full sharp under a microscope, to see what the toothy-style edge actually looks like up close. And then for a bonus what the edge looks like after this rope-cutting test.
Yeah, there's definitely something to this. I tried it, and I have some observations: 1. It's super fast to sharpen like this. From a non-paper cutting edge it took 3 minutes on s35vn to get scary sharp. 2. Strop the smooth side only, just wipe the rough side a couple of times to de-bur. And watch your angle on the strop. It's easy to mess the micro serrations up if you come from too high an angle, strop at the same angle you sharpened at. 3. The diagram at the end is, as far as I can tell, spot on with how it works. It's a micro serration that wears down slower than a mirror edge. But I don't know why. 4. Keep an eye on the edge centering, swap rough and smooth sides once in while. This is a monster edge, far sharper than anything I could hope to do in the amount of time it takes to do it.
Pete has my custom Opinel (sharpened this way) as well, he will test it soon. Should give us an idea of how it performs on a budget Steel. This is Gabe.
@@EDCwhistlesSCRATCHCARDS it's complicated. The blade is Opinel by brand, and it IS their inox steel, but I would not strictly say it's an "Opinel". It began it's life as an Opinel kitchen paring knife, and I turned it into a folding knife with linen micarta handles - because no one is building a slicer that is thin enough for me, so I built it myself. Pete is planning to test it together with the surgeon's scalpel I sent him as a combined video of "Hyper-Slicers".
Right after your previous video I sharpened a pairing knife using 45 microns on one side and 6 on the other followed by stropping. A crappy steel, it was sharper than ever as I use it every day. Not scientific (which your rope tests essentially are) but promising. One aspect of the slicing paper test (I use newsprint) is the sound. When blades become super sharp the cuts are virtually silent, a real tell. Anyhow, thanks for another worthwhile video.
Tried this on an s30v military at 17 degrees per side on a KME.140 grit on one side, 1500 on the other,stropped with 4 micron , .5, and .025 micron. Stroller thE 140 side only for burr removal. Edge was both fine and super bitey. Easily S-cute phonebook paper and is also super sticky. Thanks for letting us know about this and for all you do for us.
Did you do just one side with the 140 grit,, then flip the knife to do the other side with the 1500? Also, on the 1500 side, did you work through your stones up to 1500?
For EDC the last few years I go somewhere between 220 or 320 grit for the full bevel, and make sure the edge is clean off those stones. Then I use a 16000 grit stone at a slightly higher angle to get the very apex with maybe 5 light passes per side. It leads to relatively nice push cutting (push cut phonebook paper easily) with the slicing aggression of the coarser grit.
I'm going to give this method a try. The knives I carry stay sharp for a very long time. (K390, Maxamet, ZDP189) It is super hard to notice a bump in performance. I really appreciate the effort to test and measure the results...
Try both sides at 240 then hone on a fine ceramic a dozen times. Coarse edges should cut rope longer than a keen edge. Edge “keenness” types need to match your task. Like racing tires or snow tires on a high performance car, it depends.
Yep, slice vs. push cut. Now, the question of how much a given person's typical use will lean one way or the other is something for us knife people to agonize over individually. jajajajaja
You must not have heard what the edge put on this knife was. Coarse on one side and fine on the other. I don’t think this guy needs advice from anyone on sharpening.
It is my theory that the polished side is like the chisel grind on a serrated edge, the coarse is obviously like the serrated side. I think the polished side supports the coarse side much like Spyderco,s serrated edges.
Dear Pete, I've come up with a new sharpening method. You do one grit per 3/4". Give the entire edge a "striped" look. You also invert the grit on the other side of the blade for any given stripe. For example, this scale working like: "showside/lockside". My tip is 0.1u/100 grit, the belly begins at 1500/600, it continues to 1u/400 followed by 800/2200 and the heel of the knife is 100/0.1u. This creates a matrix of jagged hell that rips through material and actually grows sharper with use. This edge is best achieved with a Wicked Edge, since the stone width is close enough for "stripe" width. Can't wait for the video of you replicating it. I have a feeling it will be your big break. Cheers. 2,200 push cuts through the finest twisted sisal in the northern hemisphere and the edge was actually sharper then when I began.
Cedric!!! This is great! But you're making it sound like this sharpening method is more work to do. If I am understanding it correctly it takes half as long for me when I tried doing it. I just used a cheep old lansky sharpener and did coarse and 280 grit on both sides then just favored one side with the rest of my grits until I had that one side polished. Then I finished both sides with a leather strop and polishing compound to remove any burr. And if you are worried about the edge getting uneven wear then just favor the 250 side a bit more before starting on the other side with the higher grits. I did it this way and got a better edge than I normally get with my Lansky. And yeah, I don't think it's necessary to switch back and forth from one side to the other. Just get them both to 250 and blast the one side all biased like. Leave the 250 side behind and get back to it in the end with the leather strop. That worked for me any ways
Try out k390 or rex45 with 400-600 on one side and 2000 grit on show side. K390 seems to really benefit from sharpening with this method. Looking forward to you experimenting with different steels, grits, angles using this method
I tried to approximate this sharpening scheme on my QSP Penguin with my Lansky ‘controlled angle’ system. Initially, I used the coarse (purple) diamond hone on the show side bevel at 20 degrees and went up the grits through the white ceramic hone on the other side. I stropped both sides with 0.5 micron diamond paste on a leather Lansky hone. The knife shaved hair and sliced newsprint paper but didn’t seem to slice wood (pine) as easily. Definitely more drag when whittling. So I took the show side bevel up a grit to the medium diamond (orange) hone and re-stropped. The knife then shaved hair easily and sliced pine well. I grabbed some corrugated cardboard and sliced off 30 pieces. Still shaved hair. Huh. Obviously I don’t have to take both sides of the knife up to the ultrafine grits to get a good sharp edge. This certainly simplifies sharpening. The Penguin is D2. I’ll have to experiment with some of my 440C Ganzo and 8CR knives to see what happens.
Gotta try on a few knives right away. DMT 325 or 220 on one, and ceramic 6-8000 on the other. I would assume that the micro serration works great for softer materials, but less ideal for harder cutting tasks. Once the serrations “break” my guess is that it’s then going faster downhill, than a dual super polished bevel. Lots of guessing. : D
I'm going to need to see if I can reproduce something similar to this on my Ken Onion WorkSharp. Might not get quite this kind of results, but it seems like it'd be a very utilitarian edge in so many ways, and utility it's my jam. Never did care about mirror edges of any of that.
I have a wicked edge gen 3 with a ton of stones and a large knife collection. I want to try to replicate these results on my S30V military but problem is I'd need to locate the same brand rope and a similar wood cutting board
Any update on this edge? I have done it on a few nights to varying degrees of success never anything less than on par if not better then symmetric grit edges
Sounds like that method is creating micro-serrated edge. Neevesknives talked about it, that some steel perform better if you do them with for example 600grit stones instead of mirror polish, because the small "teeth" the coarser grits leave help the edge to bite into material.
Dude I swear to God I had the same exact idea not that long ago but never pursued it I'm gonna have to try it now... I'm so torn between polished vs gritty edges..leaning towards toothy/gritty overall and there does seem to be something about diamond abrasives in particular lending itself well to a toothy finish.
Been doing it for years. At least 30+ starting with 154-M and D-2. Blade forum members laughed at the idea. The all mighty cliff stamp said it was impossible! He said a lot! KnifeMaker/ Retired after 47 years in the Shop. Mentors, H. Mcburnette, George Herron, Jimmy Lile, Clay Gault, Bob Loveless and Jim Merritt.
Would like to know the hardness of the blade, I assume since it's CPM M4 that its heat treated, what is the Rockwell C scale? another steel would be CPM 10V should also produce I would think even more cuts before dulling, but these sintered metals can be brittle so there's a point between long lasting edge and possible chipping to be aware of good video thanks for making it
I sharpen by hand holding the stone in my left hand. I have always had crossed grain edges. Though I don't use different grits per side. I stopped doing razor buffed edges a long time ago because a buffed edge isn't useful for an EDC. A nice "butcher's edge" works for most things. Unless you want to carve wood or cut leather. They require a buffed razor edge. A scalpel is only about 600 grit.
atomedge here. It's just a similar method of getting a "scary sharp" edge or sticky edge (Big serrations for slicing aggression made to a thinner apex by using a finer stone to thin the larger "teeth"). Picture giant serrations at the edge with micro serrations at the apexes of them. You'd be able to get this if you say, did a 400 degree edge at 15dps, raised the angle literally 1 degree per side on the KME then did 2 alternating passes a side with a 2000 grit stone, then stropped it a bit.
Thanks Gabe! everybody will be excited to see your method tutorial. Thanks for introducing it through this great channel.🙂👍thanks again, jas frm Aotearoa 🌏
Wow, that hit the spot)) Wonder how maxamet and rex 121 would perform with the same type of an edge) Great to see new vids from you Pete, kind of missed ya, cheers mate.
@@johnscarborough4746 Yeah its looking to be about time he develops an automated version of the test to save himself from carpal tunnel .. I speak from experience he really needs to stop.
I would like to get a knife in k390. I am thinking either the Pm2 or the stretch 2 coming out. I have not handled the stretch 2. What is your opinion on the 2 knives since they are quite similar. The lock is not a factor. I am thinking blade shape and how it feels in the hand. Thank you
Very cool idea, but I'd like to see the performance of a coarse edge on both sides. I am aware that you tested a 600 grit edge and found it to be better than a mirror polish, but can you test a 250 grit edge as well? I struggle to understand the benefit of taking one side to a 6000 grit...
Do you think using this combo edge would garner the same benefits on a mid range steel? S35, 14C, D2, etc? Or do you think the combo is more beneficial to a steel with a higher retention to begin with?
This may very well be a scientific breakthrough in the knife community
Right?

Well, the only way to find out is to try it yourself. This is Gabe, here is a short tutorial on how I sharpened the knives here, it's super easy to replicate, and you could test it any way you want:

Hello there outdoors55..
Read the scienceofsharp blog and come to a conclussion yourself.
I'm going to give this method a try. The knives I carry stay sharp for a very long time. (K390, Maxamet, ZDP189) It is super hard to notice a bump in performance.
I really appreciate the effort to test and measure the results...
That method basically creates a micro serrated edge on one side. I do something similar to my edc's.
I am going to try this out! I am amazed that this has not been tried before but it makes sense. My next sharpening task is going to get this edge! Very cool that Gabe did this and sent it to you and you tested it! Thanks so much!
This is a Beautiful Thing; it makes me happy.
Man I love this channel. Great blend of comedy and facts.
I would love, love, LOVE to see what the edge looked like when full sharp under a microscope, to see what the toothy-style edge actually looks like up close. And then for a bonus what the edge looks like after this rope-cutting test.
Yeah, there's definitely something to this. I tried it, and I have some observations:
1. It's super fast to sharpen like this. From a non-paper cutting edge it took 3 minutes on s35vn to get scary sharp.
2. Strop the smooth side only, just wipe the rough side a couple of times to de-bur. And watch your angle on the strop. It's easy to mess the micro serrations up if you come from too high an angle, strop at the same angle you sharpened at.
3. The diagram at the end is, as far as I can tell, spot on with how it works. It's a micro serration that wears down slower than a mirror edge. But I don't know why.
4. Keep an eye on the edge centering, swap rough and smooth sides once in while.
This is a monster edge, far sharper than anything I could hope to do in the amount of time it takes to do it.
Im curious now what a budget steel could do
aus8a coarse dmt is great !
Pete has my custom Opinel (sharpened this way) as well, he will test it soon.
Should give us an idea of how it performs on a budget Steel.
This is Gabe.
@@homeslicesharpening inox or carbon version ?
@@EDCwhistlesSCRATCHCARDS it's complicated. The blade is Opinel by brand, and it IS their inox steel, but I would not strictly say it's an "Opinel". It began it's life as an Opinel kitchen paring knife, and I turned it into a folding knife with linen micarta handles - because no one is building a slicer that is thin enough for me, so I built it myself.
Pete is planning to test it together with the surgeon's scalpel I sent him as a combined video of "Hyper-Slicers".
Love the data you present with documented facts it's GREAT.
Right after your previous video I sharpened a pairing knife using 45 microns on one side and 6 on the other followed by stropping. A crappy steel, it was sharper than ever as I use it every day. Not scientific (which your rope tests essentially are) but promising.
One aspect of the slicing paper test (I use newsprint) is the sound. When blades become super sharp the cuts are virtually silent, a real tell. Anyhow, thanks for another worthwhile video.
Tried this on an s30v military at 17 degrees per side on a KME.140 grit on one side, 1500 on the other,stropped with 4 micron , .5, and .025 micron. Stroller thE 140 side only for burr removal. Edge was both fine and super bitey. Easily S-cute phonebook paper and is also super sticky. Thanks for letting us know about this and for all you do for us.
Did you do just one side with the 140 grit,, then flip the knife to do the other side with the 1500? Also, on the 1500 side, did you work through your stones up to 1500?
For EDC the last few years I go somewhere between 220 or 320 grit for the full bevel, and make sure the edge is clean off those stones. Then I use a 16000 grit stone at a slightly higher angle to get the very apex with maybe 5 light passes per side. It leads to relatively nice push cutting (push cut phonebook paper easily) with the slicing aggression of the coarser grit.
When you slice paper to check progress.
Does it make any difference to cut with left to right and right to left?
Cheers

This is the best channel on youtube
Try both sides at 240 then hone on a fine ceramic a dozen times. Coarse edges should cut rope longer than a keen edge. Edge “keenness” types need to match your task. Like racing tires or snow tires on a high performance car, it depends.
Yep, slice vs. push cut. Now, the question of how much a given person's typical use will lean one way or the other is something for us knife people to agonize over individually. jajajajaja
You must not have heard what the edge put on this knife was. Coarse on one side and fine on the other. I don’t think this guy needs advice from anyone on sharpening.
It is my theory that the polished side is like the chisel grind on a serrated edge, the coarse is obviously like the serrated side. I think the polished side supports the coarse side much like Spyderco,s serrated edges.
This method has made my pm2 stay sharp for so long my mind is blown
Thank you for showing this method. Really neat.
Dear Pete, I've come up with a new sharpening method. You do one grit per 3/4". Give the entire edge a "striped" look. You also invert the grit on the other side of the blade for any given stripe. For example, this scale working like: "showside/lockside". My tip is 0.1u/100 grit, the belly begins at 1500/600, it continues to 1u/400 followed by 800/2200 and the heel of the knife is 100/0.1u. This creates a matrix of jagged hell that rips through material and actually grows sharper with use. This edge is best achieved with a Wicked Edge, since the stone width is close enough for "stripe" width. Can't wait for the video of you replicating it. I have a feeling it will be your big break. Cheers. 2,200 push cuts through the finest twisted sisal in the northern hemisphere and the edge was actually sharper then when I began.
Great as usual Pete. Love these tests. Don't know why. Just do. Now, where's my sharpening stones!
You have to get the guy to show us how he sharpened the thing. Thanks for going through the work!
Cedric!!! This is great! But you're making it sound like this sharpening method is more work to do.
If I am understanding it correctly it takes half as long for me when I tried doing it.
I just used a cheep old lansky sharpener and did coarse and 280 grit on both sides then just favored one side with the rest of my grits until I had that one side polished. Then I finished both sides with a leather strop and polishing compound to remove any burr.
And if you are worried about the edge getting uneven wear then just favor the 250 side a bit more before starting on the other side with the higher grits.
I did it this way and got a better edge than I normally get with my Lansky.
And yeah, I don't think it's necessary to switch back and forth from one side to the other. Just get them both to 250 and blast the one side all biased like. Leave the 250 side behind and get back to it in the end with the leather strop.
That worked for me any ways
Try out k390 or rex45 with 400-600 on one side and 2000 grit on show side. K390 seems to really benefit from sharpening with this method. Looking forward to you experimenting with different steels, grits, angles using this method
Pete spoiling us with the frequent uploads
Have you seen the Horl 2 sharpening system. It's meant more for kitchen knives but does a 20°. Amazing planetary gear set inside.
I wonder if you could use that method on a sandrin blade or will it even sharpen the same.
This is so interesting. I’m gonna have to try this on my KME. Thanks for the great content.
I tried to approximate this sharpening scheme on my QSP Penguin with my Lansky ‘controlled angle’ system. Initially, I used the coarse (purple) diamond hone on the show side bevel at 20 degrees and went up the grits through the white ceramic hone on the other side. I stropped both sides with 0.5 micron diamond paste on a leather Lansky hone. The knife shaved hair and sliced newsprint paper but didn’t seem to slice wood (pine) as easily. Definitely more drag when whittling. So I took the show side bevel up a grit to the medium diamond (orange) hone and re-stropped. The knife then shaved hair easily and sliced pine well. I grabbed some corrugated cardboard and sliced off 30 pieces. Still shaved hair. Huh. Obviously I don’t have to take both sides of the knife up to the ultrafine grits to get a good sharp edge. This certainly simplifies sharpening. The Penguin is D2. I’ll have to experiment with some of my 440C Ganzo and 8CR knives to see what happens.
Love the content! glad to see the Knife Lab up and running inn a Pandemic-proper method :-) thanks Pete!
Man, love that sketch.
I am most courius if this sharpening method shows simmilar improvements on simpler steels like 1095 or O1.
Gotta try on a few knives right away.
DMT 325 or 220 on one, and ceramic 6-8000 on the other.
I would assume that the micro serration works great for softer materials, but less ideal for harder cutting tasks.
Once the serrations “break” my guess is that it’s then going faster downhill, than a dual super polished bevel.
Lots of guessing. : D
what about full polish, then one side polished one coarse, then full coarse?
Gabe is like the final boss!
Gabe the edge wizard
I'm going to need to see if I can reproduce something similar to this on my Ken Onion WorkSharp. Might not get quite this kind of results, but it seems like it'd be a very utilitarian edge in so many ways, and utility it's my jam. Never did care about mirror edges of any of that.
Does it make a difference which side you sharpen first? Or what direction the scratch patterns go?
I have a wicked edge gen 3 with a ton of stones and a large knife collection. I want to try to replicate these results on my S30V military but problem is I'd need to locate the same brand rope and a similar wood cutting board
Any update on this edge? I have done it on a few nights to varying degrees of success never anything less than on par if not better then symmetric grit edges
Sounds like that method is creating micro-serrated edge. Neevesknives talked about it, that some steel perform better if you do them with for example 600grit stones instead of mirror polish, because the small "teeth" the coarser grits leave help the edge to bite into material.
Looks like a really great edge have to try it out one day.
And just a warning
Don’t watch redo of healer
Dude I swear to God I had the same exact idea not that long ago but never pursued it I'm gonna have to try it now... I'm so torn between polished vs gritty edges..leaning towards toothy/gritty overall and there does seem to be something about diamond abrasives in particular lending itself well to a toothy finish.
Been doing it for years. At least 30+ starting with 154-M and D-2. Blade forum members laughed at the idea. The all mighty cliff stamp said it was impossible! He said a lot!

Would like to know the hardness of the blade, I assume since it's CPM M4 that its heat treated, what is the Rockwell C scale? another steel would be CPM 10V should also produce I would think even more cuts before dulling, but these sintered metals can be brittle so there's a point between long lasting edge and possible chipping to be aware of good video thanks for making it
Please ask him which stones he uses and for a possible tutorial, I still dont quite follow whats going on here, im a bit daft
I agree with this
I’ll have a tutorial out in a few days. Pete will share it. This is Gabe.
Damn imagine one of his edges on maxamet
GOOD JOB, NOW I MUST HAVE A COARSE DIAMOND STONE, now I wonder about VG-10, BD1N, XHP, etc
Ah man this is exciting stuff. Good on y’all Gabe and Pete! Music was on point my man
I sharpen by hand holding the stone in my left hand. I have always had crossed grain edges. Though I don't use different grits per side. I stopped doing razor buffed edges a long time ago because a buffed edge isn't useful for an EDC. A nice "butcher's edge" works for most things. Unless you want to carve wood or cut leather. They require a buffed razor edge. A scalpel is only about 600 grit.
Cedric I love your knowledge buddy. Will Maxamet steel stay sharp longer then M4.
That's a great result for m4.
Insane!
atomedge here. It's just a similar method of getting a "scary sharp" edge or sticky edge (Big serrations for slicing aggression made to a thinner apex by using a finer stone to thin the larger "teeth"). Picture giant serrations at the edge with micro serrations at the apexes of them. You'd be able to get this if you say, did a 400 degree edge at 15dps, raised the angle literally 1 degree per side on the KME then did 2 alternating passes a side with a 2000 grit stone, then stropped it a bit.
So when is the sharpen yourself a Gabe-edge video being released? Oh and your local ropedealer must be a wealthy man by now haha
What sharpener system that you use? What is your course side? Thanks from Portugal!
Thanks Gabe! everybody will be excited to see your method tutorial. Thanks for introducing it through this great channel.🙂👍thanks again, jas frm Aotearoa 🌏
Have you ever made a total of all rope cuts in knife testing you have made?
We've secretly rebladed these text knives with REX-121 to troll Pete. Let's see how long it takes him to notice.
Wow, that hit the spot)) Wonder how maxamet and rex 121 would perform with the same type of an edge) Great to see new vids from you Pete, kind of missed ya, cheers mate.
And s110v
I think it would be the last time we saw Pete doing anything for months after the repetitive motion injury he'd get from those two steels.
I'm going to try it with 4116 😁
@@bushcraftingmuslim Be interested in seeing if this method improves performance on softer steels.
@@johnscarborough4746 Yeah its looking to be about time he develops an automated version of the test to save himself from carpal tunnel ..
I speak from experience he really needs to stop.
Very very interesting 👍👍 thanks for sharing 👍🏼
This is brilliant 👍 I'd love to see a sharpening guide on this new technique!
I would like to get a knife in k390. I am thinking either the Pm2 or the stretch 2 coming out. I have not handled the stretch 2. What is your opinion on the 2 knives since they are quite similar. The lock is not a factor. I am thinking blade shape and how it feels in the hand. Thank you
I wonder if one could use a spyderco sharpmaker and simply use a coarse and a super fine stone at the same time?
Would it help your arm if the cutting surface was lower?
Very cool idea, but I'd like to see the performance of a coarse edge on both sides. I am aware that you tested a 600 grit edge and found it to be better than a mirror polish, but can you test a 250 grit edge as well?
I struggle to understand the benefit of taking one side to a 6000 grit...
It's amazing what you are willing to endure for your art !!
Would love to see an update on this edge!!!
You're a goofball and we love it!
I have that M4 para 2! Best steel I've ever used, tougher than maxamet.
M4 about to get the clout it deserves
Where are we with this sharpening method?
Be interested to see what a 240 grit edge stripped would do without the fancy double side.
Do you think using this combo edge would garner the same benefits on a mid range steel? S35, 14C, D2, etc? Or do you think the combo is more beneficial to a steel with a higher retention to begin with?
Thanks Pete, I really appreciate what you do for our community. But please take care of your hands that’s gotta hurt.
