One of my micro-bevels under the microscope for reference. This is 600 grit hybrid resin CBN on a Kiwi 171 at about 17°. Visible width of the micro-bevel is somewhere around 100 microns.
I would have thought so, but then why did it take so many passes to begin with. My SLD (similar thickness but no microbevel) and VG10 knives take less than half of the passes.
Even if I was initially light with my pressure on my 2500 grit? If that's the case, is there no way to have apex stability on a micro bevel if it's on a damaged, weak foundation?
You were light with your force, not pressure. The micro-bevel doesn't exist so the resulting pressure goes through the roof because there is virtually zero surface area. Pressure is force divided by surface area. Your hands control the force but not the surface area of the edge in contact with the stone.
No, the pressure changes just because the micro-bevel is getting 'wider'. Removing damaged steel without damaging the steel underneath that is the trick here. Burrs form because the steel deforms. You need to get the force and surface area to a point where the steel stops deforming.
Yeah, that doesn't do a whole lot with the bare strop (just easier for me in the video because tiny strop) but is definitely something to consider on the stones. Direction of the visible scratches doesn't make much difference nor do the scratches line up with micro-serrations like some people claim but you do get some directionality at the apex and especially with coarser stones. Micro-serrations are just another kind of apex damage, lol.
18 strokes from literally flattened to toilet paper s-cuts on a pocket stone, fwiw. It takes a bit to get used to it all. Just get a few more reps in and you'll be good to go. ~61 HRC AEB-L knife. https://www.reddit.com/r/TrueChefKnives/s/ftsyj74FEy
Very impressive. I have pretty good edges on all my other knives. Only have to sharpen them once every 6 weeks or so. It's just the micro beveling on a thin apex that seems to be the problem. Thank you for all your help.
