US Patent 7413228 Hard flex tweezers

An improved tweezers, particularly adapted for grasping small parts, has a first arm and a second flexible arm joined together at first ends to form a pair of tweezer jaws at second ends. A flexing of the flexible arm is accommodated as by incorporation of an arcuate portion of the first arm such that, when the arm is flexed by the application of a force, the jaw end of the flexible arm is displaced from jaw end of the first arm to open the tweezer jaws. When the force is removed, the flexible jaw returns to a rest position to apply a gripping force to an object between the jaws.
