Yet a greatmany will work away trying to cut a piece of coldsteel, while the chisel will barely mark it, but insteadthe chisel bruises up, because it has been used on hotmaterial and has lost its temper. But the blacksmithdoes not think of this, consequently he puts the blameon the steel which the chisel is made from and thendecides to heat the piece (he is going to cut), so thathe may cut it easier. But it is a poor theory as with agood heavy cold chisel he could cut off cold, threepieces (up to a certain size), while he is heating onepiece.
