The No. 391 Dead Blow Hammer 3 lbs, made by C.S. Osborne & Co., features a one-piece black polyurethane construction that is weather-resistant and maintenance-free. Its head is filled with shot (small dense metal pellets) to absorb impacts and minimize rebound, while the grooved handle with a stubbed butt provides a secure, confident grip. Ideal for working with copper, aluminum, and other metals in auto body and industrial applications.
