>>474705the befits are much better wound healing, and less tissue stress. lower risk of cutting residue causing infection etc. metal can leach and rust obsidean is quite chemically stable. (pic related a medical scalpel)
>can it keep any kind of an edge?they hold a edge well to some extent since they don't get dull they refracture. and if geometries of the new fracture is good then its just as sharp as the old one. but since you need to optimism direction,angles and force to produce the shockwave for the sharpest of fractures, chance are the random fractures will dull the knife over time.

in general it can do all cutting jobs of a knife,
so it can be used for lots of things out doors like
dressing game

should even work to make fire in a flint and steel way.
things it can is stuff like hacking, battoning, prying.
tl:dr its basically a ceramic knife.
