@@whywouldyoucare Japanese knives are made of softer steel, so they can be sharper, but the edges don't last as long as German steel knives, which in turn, are difficult to sharpen due to the hardness of German steel. Japanese knives are also asymmetrical even to the point of one side being completely flat and the other side having a very acute angle to the edge.

As an engineer that used to work in the packaging industry and prior a person that worked in shipping. That box is nothing like I've seen before, other than in furniture making. Very cool.
I was wondering that too, but the consistent ridiculously low readings make me think whatever the actual score was was too low for the test and lower than 100 or whatever
A high end hand made Japanese knife generally have around 90-120 points and it's already considered razor razor sharp, a Japanese master sharpener can reach 40 points maximun so getting numbers near to 10 is unthinkable
ill try to explain it in simpler metrics. if the scale was converted to speed, where 1000 is avg walk speed and absolute 0 would be lightspeed, getting 10 or less would be like hoping to achieve space travel speed, but on earth in atmosphere. quite impossible. the edge would literally have to be like 1 atom thin and the edge angle shallow enough not to hinder the atomic edge too much. we are talking seethrough metal sheets kind of edge. Im thinking the scale is not accurate enough or the measures are not being updated fast enough to meassure such a small and fast impact so it just basically takes the first value it got and because it didnt update in time to get the value of force applied at the breaking point of the fillament, its stuck with the first (or last) value it actually meassured. thats why he tried doing it slower. or it could be faulty fillament being either badly manufactured or maybe it was tensioned close to snapping point.
You should get a microscope with enough accuracy to see the edge and surface of a knife. That can tell you a lot about the quality, the sharpness, and the material properties. In fact, if you can measure the width of the sharp edge (which does seem ridiculous) you can directly observe how sharp it is, as opposed to indirect observation through testing.

I started out being curious about Japanese knives and ended up watching sharpening videos on your channel because I wanted to be prepared. Fast forward a few months and I held a workshop for knife maintenance with nothing but a simple combo stone. My colleagues were really happy seeing their knives whizz through A4 paper like butter. Thanks a lot Ryky! Ps: those knives seem unreal.
It's not just the skill of the sharpener and polisher, but the maker of that steel. The grain structure has to be so refined that it's even possible to get an edge that fine. This is nothing short of magic to achieve such feats. Well done to everyone one involved in the making/refining process!
I bought a rada fillet knife and was expecting average performance, my uncle used his sharpness tester and it scored an average of 56 after 6 tests. Never in my mind did I think something so cheap could perform so well and hold an edge as well as it has
Filet knives are very very thin stock + have a strong curve to them, both things which give a higher score on a flawed and imperfect system less BESS. That particular knife you mention has an intense sweeping profile, all of that curve enables it score much lower than a flat profiled blade would even given the same level of keenness.
I just love how excited he gets over knives, it shows he really loves what he does and has a passion for it. I'm actually jealous that he has found what he loves in life this much.
I TRULY hope you understand what kind of demand there is going to be for these knives and across the entire offering. I was planning on making a few knife purchases, but will definitely be holding off for now until these are available. KEEP US POSTED!

You know when you think about it knives really are just sharpened pieces of metal. However, I cant quite explain it but there is something special, almost magical about knives and edged weapons. All the work, effort, and science that goes into crafting these sharpened hunks of metal makes them special somehow. I can completely understand why swords and knives were held in such high regard throughout history. From king Arthur's Excalibur to the samurai believing the sword had connection to their soul edged weapons have transcend being just sharpened pieces of metal and become part of the human story. I completely understand why we all watch this channel and drool over these amazing and badass knives.
Best episode EVER! This clearly demonstrates what REALLY sharp apex looks like. Thanks so much for putting these edges on the BESS Tester. I’m sure I’ve never cut with an single digit (BESS) measured knife but now I know it’s possible thanks to you. It will be fun to try and get that sharp even if impractical in my world. I wish to try anyway! :D Beautiful knives with a wicked bite! Wow.
I have the PT50A BESS same tester, the filament spool can vary pretty wildly depending on how much tension you pull before locking it down. You really should use either use a weight to pull the line tight or just use the clips (more expensive). This is all based off of using my Wicked Edge Pro G3 to sharpen my Shun I use mostly. 30-50 points difference on my Shun is normal when using the certified spool of filament when hand tightening. Using the prewired clips, the variance is much lower and more in the 5-10 point range. My Shun reprofiled to 14 degree freshly sharpened and stropped is typically in the 45 range when I test it with premade clips.
Dude, your expertise and range of knives has grown massively over the last 2 years when you first appeared in my feed, you're back in my feed again and you're killing it!
Sabol brothers seem to be very technical in their approach. I'm curious to learn the steels of construction, but when I hear Ryky say that some are at or higher than Rc 70, there's definitely going to be some high alloy, high W stuff in here! They look really well made and if you think they're sharp, well...they're sharp!
I love how at 3:40 you say you’re bored with knives but then at 9:23 you have a big smile and start slicing paper 🤣 I stumbled across your video trying to find a good sharpener for my pocket knife 🤣 but your enthusiasm made me watch this whole video. Great content.
I want to thank you for the content and the indepth information you provide for the knives. Definitely got me into buying some Damascus kitchen knives and how to respect them, clean them to properly store them and everything in between. I have learned how sharp the knives are where I couldn't feel it till I seen some red on the potatoes I was cutting. Cleaned up the finger and started bleeding a bit more quickly then bandaged. Next day I checked up that knick was a little longer and slightly deeper than I expected. Plus super scary using the first few times and a nail got caught by the blade and thankfully I stopped cutting and looked at my thumb nail. It damn near sliced threw the edge of the nail with the greatest of ease.
What you say about caring for knives from A to Z is very true. That includes learning how to use them. A sharp knife will "nick" through all three layers of skin, and yes, it does bleed for about 10 minutes. If you ever sharpen a knife for a friend, check how they use it. You can get a clean bevel, nice and even, then lightly drag the edge over a high grit stone to dull it down a bit to 250 Bess. Attach a warning label if you don't. Really.
5:20 appreciate that so much, there’s so many different things that make a great knife especially for kitchen work and you being upfront about that has definitely convinced me to try one out
Those are sharp knives indeed, they would be good enough to use in a nice sushi restaurant for slicing sashimi, probably 12k grit stone would yield a knife like that. Knives definitely not for amateurs! Thanks for sharing!
I was actually writing a paper on molecular forging and while its not used for consumer production, there is tech that can hone an edge to unthinkably small levels. The materials are so expensive that its not even remotely reasonable to make for regular uses
@@MrNone-d5s I'm not sure about one molecule, but obsidian blades were actually used in olden times, possibly even today, because they can be sharpened so thin that they can literally split microbes. They were actually used for surgery back in the day because it's so good at cutting.
Alot of this is also related to behind the edge thinness not just your micro bevel sharpness. But sharpness is so way near as important as geometry in relation to food sticking. Glad to see you killing it.
i hear you. that is why i make it very clear these cutting tests are more for entertainment, and bragging rights for some, but actual cutting performance requires real ingredients
Dude I’m so excited to see Joey mantia come up in one of your videos. I’m a speed skater myself. I attended many of his training camps before he went fully to ice. It seems that even though the world is so large it is so small at the same time.
Would love to see you go to Japan to do a sharpening comparison. I wonder if the top Japanese sharpeners would get competitive and create a sharpness you dont expect.
I though you said we couldn't because it was ilegal not because they were not available yet and I was thinking "were are you at? The uk?" ... had me for a second there.
I'm surprised all of these comments are the groans from the dad-joke channel name, but aside from that having reached burrfection you csn now ascrend to your newly enlightened channel "Burrvana"
On the super-low BESS numbers... I'm wondering if the test filament was mounted with too much tension. I've never used this tester before; simply speculating.
a part of me really wants to handle a knife like these once. i wanna feel it cutting and hear the sound of these beautiful works of craftsmanship. the other part of me is afraid that once i would have gotten the chance of experiencing this level of madness, i would never be satisfied with the performance of literally any other knife.
Those knives are so sharp that if you accidentally spin it on the table with your hands in the way. Will be like those samurai show where the guys head drop off after walking away...ya that sharp.
There was a great thread on I believe Australian blade forums detailing how this is done or at least one way to do it, they used a strop loaded with 0.05 micron diamond emulsion to achieve a bess score of 25 on a folder
Yes it is done by stropping, stropping, stropping. They are probably not that good in the kitchen in this state (except for sashimi). No slicing aggression left and more like a razor. Edges like that degrade really quickly and then it starts struggling biting into tomatoes. Indicates a really good fine grained steel though.
I know how to make one of those sharpness scales read insanely low numbers. Obsidian knife. Obsidian can get an edge as small as 30 angstroms, give or take a few. Even though I know obsidian isn’t exactly known for holding it’s edge, it’s still a fun fact to know that in ancient times, when obsidian knives and blades were more commonplace, they typically could have an edge sharper than a majority of today’s knives.
@@Burrfection: I taught my niece’s new husband how to sharpen on their KDS combo wedding present last night (mostly methods I’ve picked up from you), and while listening to myself thought I might love knives a little too much too!? 🔪🤓
i'd sharpened my German kitchen knife with the Japanese sharpening whetstones and method, it was like razor blade, so i understand how does it feel to cut that paper with it.
I absolutely love your reactions to these knives. It really captures your admiration and passion with kitchen cutlery. Those knives are sooooo gorgeous! Holy shit those knives are sharp. A master sharpener must've done those edges. Just whisping through that super thin paper effortlessly. I'm insanely impressed by those edges 🤯
My favourite cut test is a seared rare sirloin steak. Most “sharp” knives can cut a vegetable no problem. Most of my SG2 knives go from single slice veggies to sawing thru cooked beef. Even roughly half my carbon steels are the same. Fujiwara steel and Ashi Hamono steel are the only knives I own that cut cooked beef as easily as a vegetable. SS honourable mention goes to Sugimoto CM2121. Cut a blackened seared rare steak and show us the real performance of those knives. Trim the fat cap and thinly sliced as possible
@@Burrfection your channel is a big part of why I got into Japanese kitchen knives. Still enjoying the 130mm fujiwara petty I bought off the site. Thanks much, that’s a hard size to find in such a quality blacksmith.
Have to get the apex right on for what you are cutting though. My CPM S90V spyderco native slices through my seared rare steaks like nobodies business. But that same edge doesn't like fibrous root foods.
In a past job I set up a knife sharpening maintenance in the abattoir industry for companies like JBS and Cargill. We would use a sharpening system called Cozzini which was a two step system. Firstly we would hollow grind and then set the profile on spiral clay wheels, and if you wanted to get your edge insanely sharp we polish the edge on a polishing wheel. We used the BESS system and if I remember correctly we would often get test results of 7. Insanely sharp. The cozzini knife sharpening machines are insane as they can take a knife from extremely dull to extremely sharp in under 2 minutes
I was thinking the same thing. I’ve had some scary sharp folders, but these are in a whole other universe. And I’ve had a Chris Reeves sebenza cause me to need a tendon stitched back together lol. I can imagine hope thin these would slice sushi grade tuna with ease.
You have what I would refer to as a dream job. Literally I have told my family that I wish I could get paid to bring tojiro knives and shapton stones to different culinary schools and butcher shops in my area
Your channel is rich and colorful! It's amazing! Browsing your video is like going back to school again! Let me learn a lot! thank you for your sharing! Wish you safe, healthy and happy every day!
I wouldn’t be upset to scratch them. I would be upset seeing them laying in a sink full of water for 3 days after I can’t find them after my kids started doing dishes.
I believe 50 on your scale is the sharpness of a double edge razor blade and to get that requires a super fine grained alloy steel. For the quality and craftsmanship of those knives is testament to that look of being in love on your face. I can only imagine how they feel in the hand. Would I use then? Probably not but would love to have just one if I could.
Just wanted to say I love your channel. I am an avid hunter and do all of my own meat processing. Sharpening knives is something I love to do very much. I just want to tell you that I have learned a lot from your channel that has made me a better at knife sharpening.
It may be that, while testing the sharpness on the machine, your fingers/hand on top of the blade and handle could be causing additional pressure instead of letting the blade rest on the fulcrum, your finger, and fall through the filament. I would love to see a follow up for science!
@@Burrfection --- OH NO!! YOU WOULDN'T BRYCKY THEM!!?? It's not as bad a watching a bullfight, but it's still awful to see a perfectly good knife brykyd.
I have yet to see factory sharpness that can't be improved upon, and that includes the best of the best Honyakis north of $2,000. Best edge out of the box I've had to date was a Mizuno Blue #2 Mizu Honyaki, and that was instantly improved with some stropping on a .5 micro poly diamond emulsion.
Hi Burrfection, I love your videos as I've been watching them for a long time to maintain and understand how to use knives. I've always been curious how I could apply these techniques or alter the techniques on a blade such as hair cutting shears because of the slight bend in the blade of shears? Thank you!
They make premade wire holders for the Bess. Would be interesting to see how those "magic" knives score with that. It would take one variable out of the equation. Did those that scored under 50 repeat the measurements again, or just that one time in the video?
@@Burrfection It was your sincere emotions and love for what you do that inspired me to buy first Japanese knife and whetstone. Looking forward to new videos!

Those knives are so sharp that if you accidentally spin it on the table with your hands in the way. Will be like those samurai show where the guys head drop off after walking away...ya that sharp.
*cuts paper
"Can you even hear that?"
Yes, and I am vibrating violently in my seat
Keeping it real
Separating physical structures from themselves on an atomic level.
There was a great thread on I believe Australian blade forums detailing how this is done or at least one way to do it, they used a strop loaded with 0.05 micron diamond emulsion to achieve a bess score of 25 on a folder
Yes it is done by stropping, stropping, stropping. They are probably not that good in the kitchen in this state (except for sashimi). No slicing aggression left and more like a razor. Edges like that degrade really quickly and then it starts struggling biting into tomatoes. Indicates a really good fine grained steel though.
The jingle while cutting the paper was absolutely beautiful! 😌
yeah. not too bad
I know how to make one of those sharpness scales read insanely low numbers. Obsidian knife. Obsidian can get an edge as small as 30 angstroms, give or take a few. Even though I know obsidian isn’t exactly known for holding it’s edge, it’s still a fun fact to know that in ancient times, when obsidian knives and blades were more commonplace, they typically could have an edge sharper than a majority of today’s knives.
8:09 the bartender when I walk in…
Be careful on swinging some of these through the air. You might accidentally open a portal.
“No! Don’t tell me you’re not 18!” 🤣
The excitement you show In every video is sooooo uplifting ... amazing content like always keep it up brother
just keeping it real. i love knives.... maybe too much?
@@Burrfection: I taught my niece’s new husband how to sharpen on their KDS combo wedding present last night (mostly methods I’ve picked up from you), and while listening to myself thought I might love knives a little too much too!? 🔪🤓
Wow just wow
i'd sharpened my German kitchen knife with the Japanese sharpening whetstones and method, it was like razor blade, so i understand how does it feel to cut that paper with it.
10 min mark is ASMR for knife cutting ears. Omg such a satisfying sound!
I absolutely love your reactions to these knives. It really captures your admiration and passion with kitchen cutlery. Those knives are sooooo gorgeous!
Holy shit those knives are sharp. A master sharpener must've done those edges. Just whisping through that super thin paper effortlessly. I'm insanely impressed by those edges 🤯
Thank you.
I really wish tried for fun to test a razer blade for shaving lol
If he says "That is not real" one more time I'm gonna lose it
gotta keep it real
i truly need these blades....
Can you test the typical sharpness you get with your hand sharpening? I'm guessing it's less sharp than the sharpest ones here?
Those knives are absolutely gorgeous
Wow... any sharper and they might start cutting through the air molecules if you swing too fast 💀
7:35 who else was scratching at their screen trying to remove that wire thinking it was a hair? 😳
My favourite cut test is a seared rare sirloin steak. Most “sharp” knives can cut a vegetable no problem. Most of my SG2 knives go from single slice veggies to sawing thru cooked beef. Even roughly half my carbon steels are the same.
Fujiwara steel and Ashi Hamono steel are the only knives I own that cut cooked beef as easily as a vegetable. SS honourable mention goes to Sugimoto CM2121.
Cut a blackened seared rare steak and show us the real performance of those knives. Trim the fat cap and thinly sliced as possible
I'd love to see some actual use performance tests.
you have good taste
@@Burrfection your channel is a big part of why I got into Japanese kitchen knives. Still enjoying the 130mm fujiwara petty I bought off the site. Thanks much, that’s a hard size to find in such a quality blacksmith.
Have to get the apex right on for what you are cutting though. My CPM S90V spyderco native slices through my seared rare steaks like nobodies business. But that same edge doesn't like fibrous root foods.
@@r1w3d That has nothing to do with the actual sharpness of the edge though, it's a grind geometry issue. The native is going to wedge very badly.
In a past job I set up a knife sharpening maintenance in the abattoir industry for companies like JBS and Cargill. We would use a sharpening system called Cozzini which was a two step system. Firstly we would hollow grind and then set the profile on spiral clay wheels, and if you wanted to get your edge insanely sharp we polish the edge on a polishing wheel. We used the BESS system and if I remember correctly we would often get test results of 7. Insanely sharp. The cozzini knife sharpening machines are insane as they can take a knife from extremely dull to extremely sharp in under 2 minutes
Pov: the silent kids at home
Dont know why this is in my recommendations but this guys passion for knifes made me giddy about them too lol
welcome
Damn. Just damn. I would love to know the magic spells they used to get those blades that sharp.
they won't tell me
0.05 micron diamond emulsion will get you to 20-30 on the bess
Chef Komatsu will probably order one of these knives from you at this rate!
haha. nice
I kinda wanna know what sharpening proccess they used to get those knives that sharp.
they won't tell me either...
I was thinking the same thing. I’ve had some scary sharp folders, but these are in a whole other universe. And I’ve had a Chris Reeves sebenza cause me to need a tendon stitched back together lol. I can imagine hope thin these would slice sushi grade tuna with ease.
@@Burrfection Well that's not very nice
Apparently the best process.
Stone sharpening finishing off with a leather polish
Unless I don't understand the machine there is a big variable here being the tension of the cord?
I love your knives. Sadly, I would never buy one that says BURRFECTION on the blade.
no offense taken. that BURRFECTION blade is just for me
@@Burrfection then 🤩🤩🤩
You just single handedly made these knife the most wanted knife
You have what I would refer to as a dream job. Literally I have told my family that I wish I could get paid to bring tojiro knives and shapton stones to different culinary schools and butcher shops in my area
You can do it!
Your channel is rich and colorful! It's amazing! Browsing your video is like going back to school again! Let me learn a lot! thank you for your sharing! Wish you safe, healthy and happy every day!
I would like to have the cool box.
I am afraid of sharpening those knives at home, knowing for sure I will scratch them.
I wouldn’t be upset to scratch them. I would be upset seeing them laying in a sink full of water for 3 days after I can’t find them after my kids started doing dishes.
You can use 3M delicate adhesion tape. I use their pink/ purple for my patterned steel knives.
u are cutting atoms with this knifes
Wow those are some amazing numbers. Very curious what kind of material you’re using for those blades.
will post about materials when knives are ready
@@Burrfection if you getting 71 HRC I wouldn’t be surprised if one was Rex 121. Curious if Magnacut is one of the steels used.
I believe 50 on your scale is the sharpness of a double edge razor blade and to get that requires a super fine grained alloy steel.
For the quality and craftsmanship of those knives is testament to that look of being in love on your face. I can only imagine how they feel in the hand. Would I use then? Probably not but would love to have just one if I could.
Ok, so where do i send my knives to be sharpened by those guys with that kind of sharpness?
seriously.....
Truly amazing!
I will be purchasing a few knives from this line for sure!
Just wanted to say I love your channel. I am an avid hunter and do all of my own meat processing. Sharpening knives is something I love to do very much. I just want to tell you that I have learned a lot from your channel that has made me a better at knife sharpening.
Love hearing from Hunters!
It may be that, while testing the sharpness on the machine, your fingers/hand on top of the blade and handle could be causing additional pressure instead of letting the blade rest on the fulcrum, your finger, and fall through the filament. I would love to see a follow up for science!
Ryky losing his mind over the sharpness of these knives was a fun way to start the day lol
Dont worry my email is not about purchasing these great knives 🙏
Damn that's sharp
Now get a brick and dull them :D Let's see if you can resharpen them to their factory sharpness.
challenge.... is on
@@Burrfection --- OH NO!! YOU WOULDN'T BRYCKY THEM!!?? It's not as bad a watching a bullfight, but it's still awful to see a perfectly good knife brykyd.
@@Burrfection: Wow… THAT’S a big challenge, and one of the few times I’d actually be sad to see an edge get Bryky’d!!
@@Burrfection holy shit, that's gonna be a challenge for more than one video...I'd say some month of testing or refining (new?) Skills/techniques?
I have yet to see factory sharpness that can't be improved upon, and that includes the best of the best Honyakis north of $2,000. Best edge out of the box I've had to date was a Mizuno Blue #2 Mizu Honyaki, and that was instantly improved with some stropping on a .5 micro poly diamond emulsion.
I own a bess tester myself and it is incredibly hard to get to even a 100. This is impressive
Hi Burrfection, I love your videos as I've been watching them for a long time to maintain and understand how to use knives.
I've always been curious how I could apply these techniques or alter the techniques on a blade such as hair cutting shears because of the slight bend in the blade of shears? Thank you!
Time to sharpen some shears!
have you ever tested an obsidian knife?
When stretching the wire you need a weight that is always the same, otherwise the result will be falsified.
thank you
They make premade wire holders for the Bess. Would be interesting to see how those "magic" knives score with that. It would take one variable out of the equation. Did those that scored under 50 repeat the measurements again, or just that one time in the video?
@@DonsWoodies
I think they will be around 40-50 but anything below that will probably not be true.
@@rainervolk666 Possibly Ryky has had actual Light Sabers made for him and not your run of the mill knives. :-)
OMG Ryky, your emotions are as amazing as these knives !!!
just keeping it real
@@Burrfection It was your sincere emotions and love for what you do that inspired me to buy first Japanese knife and whetstone. Looking forward to new videos!
Would you call that edge Burrfection?
yes.... beyond my skills actually
Hi Ricky I am 11 and I love your videos it has taught me so much and you deserve all you have worked for keep it up bro
8:16 "16! That is not possible!" - every pedophile
Due to the thin of the blade ryk that's why the sharpest looks unreal , very wow!!! and very beautiful knife wish to have one
