ABSTRACT:
A locking plier hand tool contains first and second jaw elements, wherein each jaw element has a forward end and a rear end. The first jaw element has a main recess formed by first and second contacting portions positioned at an angle to each other and a third contacting portion interconnecting the first and second contacting portions. Each first and second contacting portions has one end connected to the third contacting portion and a free end. The second jaw element is provided with an arc shaped protuberant extending outwardly in the direction of the main recess. A substantially flat member contains at least a rear part and extends between the free end of the second contacting portion of the main recess and the rear part. A substantially flat surface extends rearwardly from the protuberant. A wall is situated remotely to the protuberant. The wall has a free end substantially in engagement with the rear part of the substantially flat member when the hand tool is in the closed position. The protuberance, the wall and the substantially flat surface form an auxiliary recess offset to the main recess. This auxiliary recess restricts the workpiece while the hand tool is in the substantially open position.
