Abstract

A hand tool has first and second tool legs that are connected in a pivot region and which overlap in an overlapping region both in an open state of the hand tool and in a closed state of the hand tool. The tool legs interact with a spring such that the tool legs can be pivoted, even beyond a basic open position, into an extended open position by the user in applying manual force against the force of the spring, the spring coming into action in the case of the additional pivot movement of the hand tool legs beyond the basic open position and/or in the case of a closing pivoting movement of the hand tool legs acts on different bearing surfaces of the hand tool legs.
