I appreciate what you did here. There are some that think they a knife genius. When in fact when you look around the web you find all sorts of opinions and points of view and beliefs. I like to hear and take in as much as I can so I can decide if it's rubbish or not. Who cares about a persons voice as long as it is intelligible and is backed by solid thinking. If you don't like it just move on. I'm amazed how so many people who criticize others have in fact so little to offer in terms of healthy dialog or as in many cases nothing to offer of any benefit at all. If you offer a fair criticism to open a fair-minded intelligent discussion instead of bashing the contributor we all gain nothing, we all lose instead. I found your presentation enlightening of well-thought-out benefit to many of us knifers. Keep up the good work. I respect the time and effort that you put into sharing with us.
Cool vid Kyley, very interesting to see the blade geometry at this level of detail. If you feel like doing more like this, I think it is very worthwhile. Cheers!
Thanks for the post, Kyley. I am so grateful that you are willing to share your vast knowledge. I have always loved knives, but I can see that I am an infant when it comes to understanding all of the parameters and how they effect blade performance. Keep up the good work. God bless. John
If you take a very fine graduated ruler and show that magnified and then put the same ruler next to the image on the screen it make make it more obvious for someone who isn't familiar with magnification settings.
Yes, more microscope! Very interesting stuff. Would like to see a close up of the edge after using finer grit sand paper & stropping. Great video, thank you! :)
Great explanation. I am resharpening one of my test knives now using some water stones. I have never tried them before. I am reprofiling the edge and then I will be trying out some the test that Cliff gave me. I will take extra care with the micro-bevel.
the reason for the micro bevel is that its a lot less steel to hone and resharpen before you need to reprofile the entire convex bevel. i could have made it the same geometry without a micro, but then there is just that little extra steel all the way up the bevel to hone. the micro is still probably only 10-12 per side.
There is paradox, when you strop to razor grade, it make even more sharper, but also remove the sawtooth like edge, that reduce the cut speed ability...
Awesome video, and glad you started at a 400 grit. That seems to be a very practical grind and I can see it makes a great performing edge, with the right micro bevel of course. A comparison video to higher grit grinds might be interesting.
I have subbed BTW. Can you let me have details of the microscope you are using please? You have made my mind up and I want to get one! Many thanks, mrbluenun
thanks for sharing this, very informative ... I am new in the sharpening and believe a microscope could give me a good help ... what you think? Also can you suggest any Microscope on the cheap side that I could buy? thanks
They all look the same under a normal light microscope. In order to see the actual characteristics of the steel (aus-grain, carbides, etc.) you need to polish and edge the surface and then look under high magnification, 1000X is normal. As Kyley noted, all the light/dark spots, etc. are just the scratch pattern in the steel, they are not the carbides, etc. as some people have mentioned in other videos.
Great vids and an interesting playlist K.A.S. You just got me to sub! Tip: (For what it's worth) For a standardized size comparison which anyone can reproduce.: Use a "period" (full stop) from a phone book. - Cut out a period creating a rectangle 1mm wide by 10 mm long, giving you space for tape. - Tape this sample to one end of the knife to easily refer to it during filming.
Nice video, have you tried comparison with a new Wet Razor Blade? I know they are very much more thinner than your knife so the angle is something less that perhaps 10 degrees I am guessing. You could sharpen another knife or the front or back end of the one you showed under the microscope and instead of stopping at 250 grit carry on to 1600 and then to strops with 10, 5, 2.5, 1, 0.5, and 0.35 µ. Flicking between the two grinds you will be amazed at how fine a blade can be.
I've never even tried, and dont have abrasives fine enough to acheive this. the type of edge that can do that wont last in normal knife use more than a cut or 2. but certainly its achievable.
Awesome video! I wonder what the tip of a ball point pen looks like at that magnification? I bet the ball has all kinds of imperfections and fuzzies stuck on it etc.
found it. posted after mine. maybe he saw my awesome video, and quickly compacted it into a sage wise sounding valid piece of info. he is very relaxing to listen to.
Very good video, question I have heard it is possible to cut a hair by just dropping it on a blade... have you been able to achieve that level of sharpness? I have been able to cut a hair with very little pressure but not by just dropping one. What do you think is this possible?
I bought my son a microscope that you okug into the tv, it's able to show the threads in my work pants as a thick cable on the tv, what I would give for an electron microscope!
Love it. I want a USB microscope now. Now then, is this why you put a micro bevel on my friction folder? And, should I be looking to put micro bevels on my Falllknivens? Speaking for myself, I want much more stuff like this and trying to understand the physics. Take care, Ben
done that before for other things. it sucks. zooming issues, cannot do other off screen things. at least this way I can move the camera to show outside of the microscope.

Excellent! Thank you

Great video! I'm really getting into microscopic analysis with my sharpening as well.

very useful. deserves a textbook treaties
fascinating to see this video and what microscopic is all about thank you buddy
Amazing stuff... love it. Thanks man
Love to see different between any knife and a hardware store type utility razor or a normal razorblade
Great stuff. More please.
Very good. Thank you!
Great video thanks for sharing the information brother!
Awesome! More microscope and blade edges please.
God Video. Good info. Keep them coming.
"Tiny is what counts! ....eeh if you want good knives. that work well."
that is some bit of kit Kyley cool

Yes, more microscope videos please 👌👏
I'd like to at some point. When I upgraded to. Win 10 my scope. Stopped. Need a new one
Thank you for the post.
Would/could you make a post with difference in polishing compounds?
I am interested in sharpening wood carving tools.
wicked!

Lots of beliefs and misinformation in knife sharpening. This video is the best and to-the-point. Kudos

is that a youtube video? I thought id seen them all. will have to go back and look

Funnily enough, the ball is very smooth :)
6 years late but who cares.
What microscope are you using
found it. posted after mine. maybe he saw my awesome video, and quickly compacted it into a sage wise sounding valid piece of info. he is very relaxing to listen to.

Emily Roehrman It's possible,but doesn't mean anything

In Australia knives have "beevels"!!!
What model microscope do you use?
Danvil generic ones you find on Amazon or eBay if you search 200x or 400x USB microscope. Normally 40-100$
Niiiiiiiiice! I wonder if @virtuovice has seen this yet.
done that before for other things. it sucks. zooming issues, cannot do other off screen things. at least this way I can move the camera to show outside of the microscope.
I kept hoping you would put a human hair in the picture. Most of us can relate to hair. But not microfibers.
i wanna see the 1000 plus grits
1:57 wtf did I just heard??
i dunno.. the same as everyone else.. me talking in a boring dry voice. what do you think you heard?
knivesandstuff Moaning
Sounds like he has a ghost.
porn in the background lmao
Wtf have i just reed
Anyone here after Mr. GK?
Hey, 4:20 - I measure those things.
Just get some basic screen recording software
