Abstract
A chisel with a removably mountable blade is provided which consists of a handle for the chisel having a head region formed with a detent to provide a space for receiving a first cutting edge of the blade, while the other opposed cutting edge of the blade is arranged for a cutting operation. The space provided by the detent in the head region is constructed and arranged to prevent the cutting edge in the detent from contacting the handle portion during a chiseling operation, thereby preventing dulling of the edge prior to it being pivoted into position for a subsequent cutting operation. The blade is provided with a transverse axis at opposed sides of which are arranged a cutting portion and a rake, which cutting portion and rake are asymmetrical to the cutting portion and rake at the opposite side of the transverse axis of the blade.
