Some of my factory edges have been shaving sharp, some not.
I rarely leave any facotory edge, from any company stock.
My KZ II took some serious work at the tip. From the belly back was shaving sharp, if a bit obtuse. However, in a knife like that I expect a more obtuse factory edge.
BAD? Tiny wire edge on my first, which was perfect (meant I could strop it for a minute, and it was super sharp).
CGASH? Pretty darned sharp.
SS? Might just be the sharpest factory edge from Busse I have received. (oops, I forgot the Muck and CABS, both laser sharp from the factory).
The only Infi that I have received too dull to cut paper, was not a factory edge. It had been convexed, and was in great need of some tlc on the strop.
Sharpest though, was a FBMLE, customized by Bill Siegle. That sucker had an edge on it! Nasty sharp edge.
