ablation?"

Hello Darren,

A "bad temper" and a "temper" is the same thing ... right? Since Sikhote
is crystalline, you need to temper it properly so it doesn't end up
fatiguing as shrapnel. The piece obviously got a bad tempering, as it was
done too quickly and the back is still somewhat brittle, though the
annealing of the metal is clear in the flow-over perimeter where the heat
was applied.

Nice piece of work with an attitude ... and a great pun by Michael and
Jan. Thanks.

Best wishes, Doug
