Generally the steel used contains low amounts of carbon, which is the primary hardener in steel.
This method hardens the outside surface or skin of the metal leaving the inner core soft.
Once the outer hard surface was lost through wear, the inner soft metal quickly disappears requiring frequent replacement.
After the steel is hardened through quench and tempering, it is difficult to form into shapes for various applications.
