"Well, it would seem that somehow, the handle is made out of scorched petrified wood. The blade has been tempered to form the dark color so it won't be so bright, and as for the chip in the blade..." He thought about it for a moment, "That could have been from someone trying to pry something open with it or a down turned knife strike missing its mark and hitting something hard." He took another look at it. "By the feel of the blade though, its not metal, so whatever stone this is carved from is naturally this color. It being stone could also explain why it broke so easily."
