Igneous adze uh oh

swamp monkey:
Igneous rock like this tends not to fracture predictably.   I should say that is my experience.  Occasionally you see an igneous point from collections of archaic dart or spear points in Missouri.  Over all though the best way to shape igneous rock is peck and grind.  What I was doing should not have been a big deal.  But it was.  Oh well, start over.  :) :) :)
