Thread: Interesting Blog about Edge Development.

I wouldn't argue with any of that and for that matter I generally ignore any test or thought process that tried to prove the non-existence of something. I would say this, however, and I feel like these are fairly safe assumptions regarding the images taken.

If we assume his honing skill is average or below average then that razor when properly honed on those stones;
would probably have scratches not deeper than those shown, relative to the grit stone used
would probably have a less pronounced sawtooth edge than that shown
and would probably end with an apex width the same or narrower than that shown.

Those are the only conclusions I've drawn & they're still only probabilities.

Nothing is absolute of course, but I'd be amazed if an expert honemeister with decades of experience would pay for access to an sem and spend weeks studying a hundred different razors at every stage on multiple stone combinations and publish a detailed study, which still may or may not be considered authoritative and definitive.
