Its good to see more people starting to admit & fess up to the fact that you drop a piece of steel from above its critical temp into a sudden chilling quench there is always the possibility it might not result in just what had been intended.
The main point I would dis-agree with ED on is that if I were the Smith doing the work I would refuse to start until the owner had signed a statement to the effect it was at his request & "HE" accepted full resposibility for whatever came out.
"If" said smith had failed to warn the customer of the possibilities & received the Signed go-ahead then he of course should be held fully responsible.
