Abstract
A hammer head includes a centrally located traction surface surrounded by a peripheral striking face. The portion of the hammer head forming the traction surface is comprised of a harder material than the surrounding portion of the hammer head, such that wear to the traction surface is inhibited. The centrally located region may be formed as a separate disk with a knurled outer surface that is press fit into a cavity formed in the hammer head main body. The traction surface is preferably recessed relative to the surrounding portion of the hammer head but may also extend flush therewith.
