The flat round face spreads force evenly, making it useful for driving, flattening, and smoothing material. The ball peen concentrates force at a small point of impact, driving material radially outward in all directions. Together, these faces make the hammer useful for setting rivets, shaping metal, creating surface texture, and tapping out gaskets.

A steel collar provides overstrike protection, helping prevent damage to the wooden handle just below the head.

A tapered Torx wedge screw expands the wooden handle within the hammer eye hole to secure the head.
