Description: |
| The shape of the opening in one handle and the corresponding curve in the shank of the other handle make these pliers self-adjusting for size, while the jaw faces remain parallel to each other.

Used in conjunction with pat. nos. 1,386,149 and 1,490,902 for the KANT-SLIP plier-wrenches produced by the Allan-Diffenbaugh Wrench and Tool Co. of Baraboo, WI and the KANT SLIP P & T. Co. of Chicago, IL. |
