What are some suggestions for cooking tools/techniques for people that have arthritis? I've recently been diagnosed with Rheumatoid Arthritis, and my grip is VERY poor. I can't even make a fist anymore. A few days ago I found that cutting up a left-over, cooked chicken breast was VERY difficult. Not only the knife grip, but using my left hand to hold the meat with a fork was probably worse than the knife int the right hand.

I've seen sites mention those rocking knives and tools with wide handle. I'm more interested in wide-handled tools as the rocking knives look like they would be unable to be honed.
You should certainly look at the OXO Good Grips brand of tools, they all have fat grips that are easier to use.
