As I get older I find my grip isn't what it used to be. I have a difficult time tightening and releasing my large clamps. I solved this problem by wrapping my clamp handles with this stretchy material. I bought it at a farm store. 3 or 4 wraps is sufficient and it is robust enough to hold up to daily use. One caution if you are allergic to latex you need to buy the medical version of this product.
