Most cutters have cutting edges that are hardened by an induction heat treating process that concentrates the hardening to the cutting area portion of the tool. Induction heating uses high frequency energy to heat the cutting edge to an orange/yellow glow. While at high temperature the tool cutting edges is bathed by a severe quench that transforms the grain structure of the cutting edge material to an extremely hardened condition. This hardness extends deep into the jaw. The induction hardening process concludes with a tempering operation that reduces the stresses formed during the heating and quenching steps.
