All Wilde punches and chisels are forged from high-carbon molybdenum tool steel and individually heat-treated to make them the toughest striking tools on the market. Wilde punches and chisels are hardened the entire length with a tempered striking end.
Chisel cutting edges are sharpened and re-sharpened to give the keenest points available. Pin Punches have a reverse taper point which eliminates the punch from sticking in the work-place.
Chisels are designed to be re-sharpened once they become dull. Care should be taken that excessive heat is not obtained when re-sharpening. If the grinding temperature is not controlled, the hardness can be taken out of the immediate area. More importantly, a hard, brittle surface can be set which is very susceptible to fracture.
