Mustad forepunches are available in two models for punching E-head or city head nail holes. Both types have a wooden handle, firmly mounted in the hammer head with a ring wedge. This makes it easy to maintain and replace. The head of this hammer is made of air-hardened steel and should not be cooled in water. In general, these tools should be used at low forging temperatures, between 1,112°F - 1,292°F.
