It seems like a small shield for griping something and protecting the hand, but the spring is quite stiff. after compressing it, there isn't a lot of umph left over to hold the part with any great strength for very long. The pivot joint is not super precise nor is the jaw surface alignment. The adjustment moves the shield back and forth, there is no mechanism to lock the jaw shut.
Moving the jaws in and out of the shield does change maximum gap of the jaws, but by small amount so if its clamp its range is narrow
There are small serration on the face of the jaws. The parts are very well formed and would challenging to make as one of for a specific task so i'm inclined to think its a commercial item
Anyone recognize it or familiar with its use/purpose?
thanks
