Interesting concept, rotating the handle causes the jaws to tighten up and pinch the nut. It works better than I would have thought, but once again only where there's room for the large jaw area to fit. Won't replace your Crescent wrench. The Lock Jaw name is so common, it's hard to search for information, I don't recognize the S logo but apparently it was made in Canada!
The tool looks as though it was never used but you can own one brand new (called a Uni-wrench) on ebay- but they won't ship to Canada.
Wera has a “new” version of these wrenches called Joker.

And they're not cheap! Obviously they think its a useful tool. I'm going to put a pipe on the handle and remove a wheel nut. That will tell the tale...
