ABSTRACT:
A urethane hammer or other hand-held striking tool having a handle portion cast of a lower durometer, more flexible grade of urethane material, and a head portion which is cast around a metallic weight at the end of the handle portion. The flexible handle absorbs shocks, while the hard material of the head provides a durable, effective striking surface. The tool is cast using a two-stage process. In the first stage, the handle portion is cast with the metal weight located in its end. The handle portion is then placed in a second mold in which the weight on the end of the handle extends into a larger cavity corresponding to the head portion of the tool. The higher durometer urethane material is then cast in this cavity so as to encase the weight and the end of the handle portion.
