This Sew Mate 4-in-1 craft hammer is the perfect multi-use tool. The four interchangeable heads--iron (flat), iron (round), brass, and ABS--make it ideal for working with silver clay, woodworking, leather punching, scrabooking, quliting, and other DIY activities. The additional heads are stored in the handle of the hammer.
Use: Place objects on a flat surface. Hold the handle toward the bottom and strike firmly. Exchanging the heads is done by easily untwisting the head you'd like to replace and twisting on the correct head.
