[TheForge] h13 for chisels

Mon Mar 25 18:15:01 2002

Anealling is its bad point.  The only way I managed to aneal it at all was to
heat up in a pipe then put the hot pipe and chisel into vermiculite.  It was
still hard but a NEW file would just cut it.  Around here I can buy round stock
fairly inexpensivly but square stock has to be cut from plate so is very
expensive.
