Description: |
| A double tapered shank on the "outer" jaw slides in a double tapered slot on the "inner" jaw and handle. The alignments are slightly off, so the tapers bind and hold firmly when the two portions are squeezed together. The "outer" jaw shank may include a tire remover end, the handle may end in a screwdriver blade; the wrench was intended for use on cycles and cycle tires. |
