Abstract
A trowel handle is injection molded from two separate types of plastic. An inner core is molded together with a finger guard from a plastic providing a smooth surface of a first coefficient of friction with the user's hand. The finger guard covers the metal tang of the trowel and protects the user's forefinger and thumb during troweling. An outergrip is molded from a thermoplastic rubber providing a soft, rubber-like surface of a second coefficient of friction with the user's hand.
