Mustad creasers are available in 2 models, E-head or City head. Both types have a wooden handle, firmly mounted in the hammer head with a ring wedge. This makes replacement of the handle easy and gives the possibility to customize the creaser yourself. 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 600˚C – 700˚C.
