I'm a professional sailmaker, so i spend a lot of time at the bench hand-sewing. I typically use a medium-weight palm at work and wanted to pick up something lighter for around the house, or what-have-you.
I've only put a needle through a palm once before (and that's when i broke the needle in half). this palm makes it very hard to not put a needle through the palm; it's fairly flimsy, and the cup is in the wrong place/angle. only useful for EXTREMELY light work (most likely size 18 needles or smaller)
