This tool is a domed nylon hammer (often referred to as a pear-shaped nylon mallet), which is primarily used by jewelers, silversmiths, and metalsmiths for forming, shaping, and dapping sheet metal and wire without leaving marks or scratches.
Non-Marring Surface: Unlike steel hammers, the high-density nylon head absorbing impacts cleanly, allowing you to manipulate soft or precious non-ferrous metals (like gold, silver, copper, and brass) safely.
Asymmetrical Taper: The head usually measures about 5 inches long. It features a broader 2-inch domed face on one side and tapers down to a narrower 1-inch domed face on the other side, giving you two different radiuses for diverse dome work.
Ergonomic Wood Handle: It features a traditional lightweight hardwood handle secured to the nylon center by a cross-screw.
