The jeweler's hammer is a small (approx. 15-25 cm) and light (approx. 50-100 g) hammer. The head (approx. 7-10 cm) has one wedge-shaped end and one circular or square (approx. 1 cm). The handle is made of wood. Another model is all-metal with a short, round handle. The goldsmith uses this hammer to perform very fine and precise work, such as embossing. [MOT]
