Weapons made from stone

[Nicktacular]

Does anyone know where I can find official rules for weapons made from stone.

Well there is Deep Crystal, which, ya know, is a rock...

but for knapped tools... I think A&EG has info

I know there are specific rules for microlith weapons, specifically the macuahuitl, think dragon magazine or faerun books

Does anyone know where I can find official rules for weapons made from stone.Dungeon Master's Guide 1, page 144.

So would weapons made of stone cost the same

What kind of weapons are we talking about here exactly, beyond "made out of a rock"?
