Hammer, Assault
Assault hammers have heavily weighted metal heads and relatively light aluminum or polycarbonate grips. Hammer heads can be custom-made with designs or logos imprinted on the surface. Comet, gravity well, and meteoric hammers have weighted or pneumatically driven heads that deliver accelerated blows.
