Texas Prime Thin Chert Flint Knapping Flintknapping Preform ((FREE SHIPING))

Description

This is a very large preform made from quality Texas chert flint. See Pic for size and shape. One of my dad's old friends was a quality flint napper and his widow gave me some of his flint to sale for her. Feel free to make an offer, but keep
in mind
we offer free shipping. I
don't
know
for sure
but one buyer who bought one of the larger preforms told me in a message that it was heat treated.
