It's a temporary handle for something. The metal part above the handle is slid up into the indentations to close the two hooks and hold them onto the item to be grabbed with the temporary handle. I will say it is used by whalers to affix a grabbing point to a whale carcass
damn, that is harsh even by my standards. you are like a performance artist that pushes the limits. i am simultaneously scared and amused.
Well, we had a Mogen clamp awhile ago (for circumcisions). Maybe this is a circumcision device for the BDSM community? No anesthesia, of course.
