Where did the metallic flange on wooden Vises come from? A copy of Building Age from March 1885 describes a “Patent Metallic Vise Flange” from Ohio Tool Company. It claimed the following advantages:
- Negates the necessity of mortising the jaw of the vise which would weaken it.
- Does away with the friction and wear of the end of the head of the screw against the jaw of the vise.
- Less strength is required in tightening.
- The jaw is carried squarely and firmly.
- The flange adds strength and durability to the vise.
