Description: |
| The innovation is improved gripping surfaces on the vise jaws, created by using multiple strips of steel that can each be reversed to expose a fresh edge. See also Canada patent CA-51,964, and US patent 631,013 that addresses a shortcoming of this jaw design where the strips can fall out even when originally tightly clamped. |
