This tool fits comfortably in your hand and excels at working in tight spaces and with thin bolts and nuts. It's about 60% lighter than conventional (heavy-duty) wrenches with the same opening size, and its bold form reduces hand fatigue. With the power of a size larger, it firmly grips bolts and nuts for speedy work. I bought and used this about 5 years ago. The grip shows signs of use, but it's still perfectly usable!
