Should you ever find yourself in the position of needing to cut
someone's heart out, you can still get obsidian scalpels from some
surgical supply houses.

Some friends of mine took a course in aboriginal living, and made their
own
obsidian tools, which they used for survival over the summer. The
instructor in knapping was one of the guys who supply the obsidian
scalpels.

Presumably, he scaled up a bit for this work........it's gotta be tough to
feed a troop of hungry troglodytes on gerbil and vole tenderloins.
