Abstract: This invention is a new beginning for AN wrench users. No more uncomfortably thin AN or Bonney wrenches are needed. This wrench/tool system with separate, ergonomic handle is loaded with features designed for comfort. The separate handle is specifically designed with contoured finger grips, and gently radiused back edge resting against the palm of the user's hand. These are features that will provide the user all-day comfort. In addition, with the common blade of the wrench/tool ends, fitting the matching receiving groove of the handles, wrench/tool ends and handles of differing styles can be added, and upgraded to build a set of wrench/tool ends and handles to meet every need.
