Beadalon Rubber Bench Block for Jewelry Making, 4 by 4-Inch, Black

Use this block under a traditional steel bench block to absorb the shock from striking the steel block with a hammer. The Rubber Bench block can also be used by itself to limit the amount of marring on the front side of wire or sheet. Take care when hammering on the rubber block as the energy from the hammer will transfer back to the hammer.4" x 4" x 1" (10.2 cm x 2.5 cm).
