Sharpness is kinda subjective. I can run my thumb (carefully) across an edge and get a pretty good idea. But attempting to slice a piece of typing paper hanging by a corner is probably a little more scientific.

BTW, I have shot some sharpened G5 Montecs into foam broadhead targets, and it seemed like they got sharper for the first couple of shot. Maybe a stropping affect at work here. After a bunch of shots, though, they got dull.
