Ah, wiki ate my comment.

Stone can ABSOLUTELY be used to create an axe or knife blade. Flint knapping is an ancient (but still practiced) technique by which tools were made from stone by breaking and chipping them into the desired shape; in particular knives and axes.

So yeah, Stone Dust can absolutely be used for an axe blade.
