After 37 years of pushing pencils and typing on a keyboard at the office, my grip is not what it used to be. So I found an easy way to get a powerful yet comfortable grip on my clamp handles. First I wrap the handle with athletic tape. Then I stretch on a piece of bicycle inner tube that is slightly smaller in diameter than the handle. That's it! The tape helps hold the tube in place. If you don't have any used inner tubes, new ones are inexpensive, and a couple tubes will cover a lot of handles.
