That would probably get it done.
The burr concept works really great w/those big ol' ceramic sharpeners on good steels...My 18inAK by Himalayan Imports is RAZOR hair slinging, scary sharp. I developed the burr, flipped it, the edges met at about 27%---This is not a tool u wanna skrew around with..if u dropped it the wrong way the weight would probably carry it to the femor, ruin your foot etc...its a demon crusher chopping weapon.
This ceramic stuff is a man--made stone--way more refined, after boker gets ahold of it, sharper by definition--MOHS scale hardness 8.5, diamonds are a 10 of course.
If u went to the really fine expensive DMT stones, and used DMT Diamond paste stropping I dont see why it wouldnt work, other than technique.
How much could it take in an emergency SD situation--a stab, as apposed to a slash/slice?
It would probably snap..
The myans/aztecs(?) flint knapped thicker obsidian blades and used them in warfare...much less refined/weaker than alumina/zerconia ceramixxtures made now. The Kyocera kitchen knives are tough, not much of a point...as long as u dont hit them w/a hammer, chop ice/frozen meat, or thow them into the sink w/abandon...i see sharpening it as an "xtreme micro abrasion, polish flaking" idea.
I could be wrong. Theres nothing in the matl. soft enuf 2 create a burr with
