I picked up this tool at a rummage sale and have been unable to identify it. It appears to be professionally made but has no manufacturer's markings anywhere.
Dimensions & Features:
The jaws are rubber-faced, so it was clearly intended to grip or clamp something without damaging the surface.
I've considered watchmaking, jewelry, optician, dental, luthier, and laboratory uses, but nothing I've found is an exact match.
Does anyone recognize this tool or know what trade it was made for?
Dimensions & Features:
- Overall length: 175 mm (6.9")
- Rubber pads: 40 mm (1.6") diameter
- Maximum jaw opening: 25 mm (1") center-to-center
- One jaw is slightly convex.
- The other jaw is flat and mounted on a flex joint, allowing it to pivot in all directions so it self-aligns with the work.
- The jaws are only parallel when they contact the object.
- The handles are spring-loaded with a leaf spring.
- The knurled knob does not adjust jaw spacing or clamping force. It simply retains the ball-joint assembly and unscrews about 5 mm.
- No markings, patent numbers, or logos anywhere.
