Designed by Linda Jones, the Whammer is a must-have 3-in-1 tool for every jeweler! It's a dual-ended hammer which has one fixed-position head as well as interchangeable nylon and dapping heads. Though the Whammer was specifically created for use on wire, silversmiths will also love this compact multi-purpose tool. The permanent head features a highly-polished convex steel face which is specially designed for flattening, spreading and work hardening. The removable flat nylon head is perfect for smoothing kinks in wire and tempering color-coated and plated wires without marking surfaces. Unscrew the nylon head to secure the dapping head which can be used to accurately create texture on wires 20 gauge and upward. You're sure to achieve great results with the Whammer thanks to extra weight in the head, which reduces the amount of striking power needed, and a short ergonomic handle which enables a perfect grip and helps to improve striking accuracy.Details:Black handle6.75" x 3.5"Steel, plastic and nylon
