Hi Imorris, The PalmControl vise is a 10lbs basic vise. It is 4" inches in diameter and made from 303 stainless. It does have a detent release to the retainer holding the screw so it could be used as a low cost postioning vise. There is a batch 99% completed that will be avaiable soon. I wanted to hand engrave the logo on this first batch and I need to get that done yet.
