Abstract
An open end wrench head including first and second jaws that are adapted to engage a workpiece located in a hard-to-reach area. The jaws can include a chamfered portion on the end of the jaws that allows the wrench to be presented at an angle to the workpiece and still maximize the engagement area between the wrench and the workpiece.
