Widget Supply has a 1-1/8″ diameter face chasing hammer for $6.97. Despite looking like a giant bruiser in the picture, this hammer is actually quite light and small, with a head weight of only 6 oz. Think shaping and delicate work — not bashing things into submission.
The hammer is used for striking chasing tools as well as directly shaping malleable metals. Chasing is the forming of metal by hammering the surface with small, shaped punches against a resilient backing such as jeweler’s pitch. Most jewelers also use hammers such as this for cold forging metal against a small anvil or bench block.
