Abstract
A hand tool includes a first jaw; a second jaw rotatably coupled to the first jaw, the second jaw including a first set of projections and a first bearing surface, the first bearing surface having a first curvature; and a lever coupled to the first jaw, the lever including a second set of projections and a second bearing surface, the second bearing surface having a second curvature. During a movement of the first and second jaws from a full open position to a full close position, the first and second sets of projections are at least partially engaged to prevent a slippage between the first and second bearing surfaces that are in a rolling contact during the movement of the first and second jaws from the full open position to the full close position.
