After all, how many of us know how to chip stones so as to form
a proper stone age tool?
(raises hand) I do!! I do!!!
I was taught how to chip arrowheads as a little kid in the early 70's,
by the grandfather of a friend of mine who lived on the Pine Ridge
Reservation in South Dakota.
The old-style glass insulators for power lines, make the best
arrowheads.
The thick glass at the bottom of beer bottles works pretty well, too
(though you have to chip the curve out).
Way better than the way I do it. I forget that I have some flint
arrowheads in a box and bounce it around. The arrowheads chip very
easily.
