Review on Sliding Jewelers Diamond Stone Setting by David Skyline

Not what I expected based on the description. I was looking for grips that strong, but due to my arthritis I need an opening and closing mechanism that is operated by thumb pressure on the top so I don't have to try to rotate the barrel while holding an object in a vise to get it to tighten . They're quite usable and we'll be sticking with them as I'm sure they'll come in handy for other projects. In the meantime I will continue my search for the perfect pin vise.
