The Twister is a hardened stainless steel knock down with a rubber cap to quiet the strike. The twist is for looks and a comfortable grip.  It has a mirror polished tip for knocking down hard edges, sharp points, and stubborn to move metal. Light weight, think of stainless steel, with a nice twist to roll in your fingers. This is a great add to your tool set. It can be used as the every day knock down or as  the one to move the double seam.
