thanks guys. got a hell of a surprise this morning. driving around with my 5 yr old and i heard tink, tink tink coming from the back seat. i asked him what he was hitting. he says, "im flint knapping , just like you" . looked back and he's got this basin blade in one hand, a hammerstone in his other, just choppin away at the edge!!! after i temporarily freaked out and made sure he wasnt covered in flint and blood i laughed my tail off, said nice work but we cant flintknap while we are driving. blade is still together just lost some width.
