CARP chisels

Carp’s chisels are made of hardened HSS M2 steel. They are forged and/or milled, then hardened to 63-64 HRC, then ground and polished.

Harden

How good a chisel is depends largely on the hardness and toughness of the steel. So a lot of attention is given to hardening chisels. This is a lengthy process. It starts with heating the steel. This is done in absolute vacuum. Then the chisels are hardened in 3 steps, before undergoing another process of heating and cooling. Here, temperatures of up to -185 degrees are reached (in liquid nitrogen). Quality is strictly monitored. Between 5 and 10% of each batch of chisels is tested for hardness and toughness.
