Description

FIG. 1 is a top plan view of an open end wrench showing my new design, the bottom being a mirror image thereto;

FIG. 2 is a side elevational view thereof; and

FIG. 3 shows the action of the wrench with the longest jaw member engaging a square head member shown in broken lines for illustrative purposes only.

The characteristic feature of my design resides in the overall specific configuration of the wrench jaws and more specifically in one jaw differing in length from the other.
