ABSTRACT:
A handle of a hand tool includes two opposite wide surfaces and two opposite narrow sides. The wide surfaces are perpendicular to the rotational direction when using the tool so that the fingers except for the thumb are in contact with the wide surfaces. Each wide surface has a reinforcement protrusion extending perpendicularly therefrom and located close to the driving end of the hand tool. Each reinforcement protrusion includes a thumb area such that the user's thumb may press on the thumb area when rotating the handle.
