Throw away those clunky Allen wrenches. Overbuilt to bow tuning torque demands, this smart new ergonomic design takes advantage of the working angle and shape of your hand to make bow tuning fast and easy. Comes with 10 hex wrenches that seat in one of 3 hex drivers. The Allen style bits come with a ball-end so that the 3-way driver can be used 10 degrees off square without loss of grip in ultra tight arreas. The 1/4" driver will fit any standard hex bit, so adaptability to other jobs is virtually limitless. Bits are made of ultra tough 50CRV-A tooled steel for long life.
