ABSTRACT:
The invention relates to a self-opening hand tool (1) with two tool halves (2, 3) that cross over each other at a joint (4), in particular in the form of a pair of pliers, scissors or the like, with one half of the tool (2, 3) forming a jaw (5) on one side of the joint (4) and a handle (6) on the other side of the joint (4), with a spring element (8) of elastically deformable rubber or plastic material also associated with a handle (6), which has an opening (9) through which the handle (6) passes, and that can be moved into at least one operating position at will by turning it from a non-operating position, in which operating position the spring element (8) contacts the opposite handle (6) depending on the spread angle of the handle (6) and the generation of the appropriate restoring force. To further improve the initially described hand tool for more advantageous use, it is recommended that the handle (6) be contained in a handle case and that the spring element (8) be supported by a form fit to maintain the operating position or the non-operating position.
