To harden a steel part in a domestic environment, it must first be heated, as, for example, on a gas burner. However, the question arises: what is its holding? Pliers or forceps are not very comfortable with this, as they themselves get really heated, delaying the process. Better to hang the item on a wire, securing it with several wraps.
