A hand tool includes a work portion and a user/operator interface portion comprising a handle. The handle comprises a pair of elongated members each including a generally I-shaped cross-section. Each elongated member includes a gripping portion. The gripping portion has a first surface and a primary user--interface surface having curvatures in three dimensions and preferably defined by a plurality of constant radii. As such, the handle conforms to the hands of a user/operator and reduces or eliminates undesirable pressure concentration points. The first surface of the gripping portion is provided with a finger registration portion which receives and positions the fingers of the operator around the gripping portion. The hand tool more efficiently transfers the operator input force through the hand tool to a workpiece and provides an improved comfort to the operator.
