Solid head dead blow hammers are usually made of rubber or resilient plastic (such as ultra high molecular weight plastic, UHMW) and rely on the inherent properties of the material to absorb shock and reduce rebound. Commonly constructed of polyurethane, dead blow hammers regularly appear in solid orange or black. Composite heads and fiberglass handle models are also available, with optional shock-absorbent rubber grips. A variant design omits the handle entirely; the dead blow head is gripped directly in the hand, for use in tight locations.
