Leverage Tools Lever Wrench C-12 Welding Automatic Sizing Adjusting C-Clamp Demo

A demonstration of Leverage Tools auto adjusting LeverWrench. I had never seen these before so I thought I'd try them out.
I bought these in a box at a sale, they were covered in dust but looked unused.
There are some age stains but no indication they were used to clamp anything
I’d never seen these, they were stiff so I added a couple drops of 3 in 1 oil in the handle, which worked. There is a small adjustment wheel under the handle and just a slight turn makes a difference. These are designed to use repeatedly on different thicknesses.
What I found:
Jaw when opened naturally 1-3/8”
Jaw held open 2-3/8” (it may go to 2-1/2” I didn’t try it)
It auto-sized to the different square punch handles I used in the demo video, and an additional C-Clamp arm at the end.
