Knife Edge Geometry, Under The Microscope Part 2

Showing more information about the finer details of knife geometry under the microscope, and finishing with a little cutting demonstration.
Part 3 will show a comparison of different styles under the scope

[@SpartanJohns]

Thanks! I can say I learned a lot! Now I have to see how I can apply that!
When I think about it...what I did not know...is just pure logic!
I really liked when you showed the apex facing the camera...once it was stropped.

Looks like this was a tricky video to make. Interesting stuff, I think I've been guilty of "over stropping" lately. Thanks Kyley.

liking this microscope stuff Kyley cool

[@pennfootball71]

That was very informative. I think we should start a production knife company and make convexed folders. We can can show people are edges under microscopes instead of doing silly things like cutting meats and bending the knife until it snaps. Then we can sell the knives with a little strop and compound and a few peaces of sandpaper up to 400, 800 and 1500 grit. :)

thanks for the great info!

[@shippen2010]

That is sooo coool;.... Thanks Mate great work.... cheers

[@CliffStamp]

Nice demo on the phonebook.

[@donnya1000]

Excellent!

[@notthenutter]

Fascinating.

[@knivesandstuff]

part 3 is up :D

[@LeaveYouT]

That was a pretty good demo of burr remnants and removal.
How thin are your edges behind the cutting edge? somewhere 0.3-0.4mm ? The millie and the manix is like 0.7-0.8mm or more I think, right? It'd be nice if you could quickly measure it.
After seeing both vids, do you think that you should adjust your strop so that it contains less CrO on it? And maybe a bit melted to be more efficient?

[@LeaveYouT]

No,I'm not referring to that kind of melting.I'm referring to a bit of heat so that the wax in the paste on the strop has the chance to better stick to the strop surface.That stuff is really really small and the strop needs very very little to be truly effective. Indeed people are applying way too much and that is counterproductive they are relying on the abrasive properties way too much, when a stone is needed.You are right,5passes max is needed to remove the slight remnants of a burr.

I feel like I'm watching a Kung Fu master just telling me the answers instead of having to discover them for myself on life's journey!

[@knivesandstuff]

it is thin, but for me thats normal. as you can see my hatchet is cleaving through cow bone without much issue at all. its all about those tiny details people keep telling me are too small to measure.

[@knivesandstuff]

in part 3, the descr links to my theory video. i got many people sending messages, i just stopped approving many of them, because they insist that what I was demonstrating in theory in cad was so small that it could have no real noticible effect.. clearly not true based on the evidence shown in #3.. basically.. people that I dont know, that probably are just not understanding what I'm teaching.

[@LeaveYouT]

That's pretty thin, Thanks.

[@knivesandstuff]

i understood your meaning, but not all compounds are made of the same stuff, so they dont behave the same way. my compound adheres extremelty well. any heating will just turn it to slush. it has a much better binder than some of the ones sold by knife shops. you have to remember that what you are seeing on the video is microscopic particles attached to the steel. this is natural and inevitable when rubbing 2 materials together. its not because my compound is all floating on top and loose.

[@knivesandstuff]

I can honesty say i have never measured this or worried about it because i just test the knife and see how it feels.. however, CliffStamp might reply as he has a number of my knives now. he just told me that my cKc Hatchet is less than 0.010" at the secondary bevel.. so less than 0.25mm
vid and details here /watch?v=Pd897xda4I8

[@knivesandstuff]

on your second question. melting wont make it work better. you probably would be applying too much if you are melting it on. but honestly.. more or less.. almost every single person I see stropping is either doing way too much, or a ridicoulously way too much... fundamentals are more important than effort without understanding that dont get you far.

[@stubbybutt8839]

If you think that was a clean edge you need to look again. Whats the point of using a microscope if you only see what you want to. And you do know you sliced that convexed edged knife into that phone book. And whilest it is the better edge your never going to change anybodys mind based on that demonstration.
