Looking for large crochet hooks. Hands get stiff nowadays?

That ergonomic one looks good. I have also seen (in medical supplies shops) a 'grip' that you can slip over anything to help you use it. You'd keep your own hooks that way. These grips are made of some kind of foam or foam rubber (or something like it) and are shaped kind of like an egg; they have a hole up the middle into which you slide a pen or pencil, or other household items. The crochet hooks would probably fit fine, from what I've seen.
