Stones and edges

[spanx]

I stumbled across these images of stones and edges they produce.These pictures were done by Tim Zowada.I've seen pics here and there of magnidied edges but nothing as elaborate as these.I think one of you mods should sticky these.They would make for good reference to what a hone is capable of.

Thats really interesting! Especially in that it seems the cheap chinese 12k puts a smoother edge on the test razors than other more expensive options. (At least that's what I'm seeing in the pictures)

My 1200 DMT looks flawless under 400x (So does Seraphims). My Eschers look like a carpenters saw. Don't confuse having a straight edge with being sharp.

But I would say that the way Mr Zowada looks at his edges by tilting the razor up at 60 degrees results in a pretty good way of looking at sharpness as opposed to just bevel shinyness. I would not have thought of doing that if I hadn't seen the pics that Mr Zowada shows of his setup. My razors are usually tilted at about 45 degrees when I look under the scope.

Back to the Zowada edge pics:not only is the Chinese 12k edge impressive, but the chromox results are fantastic as well.

My scope's focal length actually requires I angle my edges up. The important thing is that an optical microscope just doesn't allow you to read the width of the edge (sharpness). You can try to use gleam breadth and some guesswork, but because different steels and different grain patterns scatter light differently, even that is just assumption. Even with the angled pictures, what you're looking at is the consistency of the edge and not the sharpness. This gives a huge advantage to both stropping motions and very slow stones. If he threw a surgical black arkansas in there (used with oil), it would be right up on top too.

+1. Optical magnification lacks the resolution to show the sharpness of an edge. We know from Verhoeven's SEM images that razor's edges have a tip width in the 0.5µ realm and below. It is highly unlikely that the optical magnification pictures we see on the various websites, that are not exactly made at lab conditions and specifications, show us any details below 1 micron. That explains why most edges polished below that level appear spotless.

Kind regards,
