Universal Magic Wrench
Whether it's round, hex, triangular, square or serrated, this new tool will grip it tightly – with no slipping. The leaf-spring loaded, serrated jaws lock in place – the gripping force is instantaneous and very firm – and the unusual shape of the gripping tip allows it to hold a huge variety of shapes. We like this wrench a lot, especially when you need to move around and have limited tool-carrying capacity. The length is 11-1/4 and weight 1-1/2 lbs.
