Heat Treating Soft Metal (Tools)
I have some cheap Harbor Freight screwdrivers and other tools that I know are made out of soft metal that I'd like to harden.
Can the tips of the screwdrivers be heat treated to harden them?
They are essentially useless since they are so soft.
If the tips are heated red hot and dipped in oil will that make them better or just "screw" them up?
