I had been looking for a reliable workholding solution for my jewelry-making projects, and this creative innovation has exceeded my expectations! Through trial and error, I found that it holds diamonds and stones firmly in place while allowing me to easily manipulate the piece for precise setting. The compact design also helps me make the most of my limited workspace. The only con I have noticed is that it takes a few uses to get the hang of the sliding mechanism, but once you do, it's a breeze. Overall, a great investment for any Industrial and Scientific craftsman looking for precision workholding.
