The present invention provides an ergonomical handle for a power tool that reduces the risk of injury to an operator's wrist or forearm by redirecting torsional forces to the operator's upper arm and reducing the force provided by the tool operator necessary to resist the torque produced by the tool. The handle includes a concave channel and a means for attaching the handle to a tool adjacent to the barrel of the tool, such as an annular collar with a substantially elliptical outer diameter. In a preferred embodiment, the channel includes an inner side wall and an outer side wall that are curved in a nonparallel fashion so as to mirror the planar and dorsal sides of a hand. In use, a tool operator inserts a hand into the channel. The side walls of the channel frictionally engage the operator's hand so that the operator may operate the tool without gripping the barrel thereof.
