How to open jars

In my boredom, I came across something I could totally use. Industrial hand wheels for all of those things I have trouble opening. Things like pickle jars or 2-liter soda bottles. All they really need is one of those wheels with the little handle sticking up! Then I'll stop hurting my hand (especially on the soda bottle tops) and I won't have to ask my husband to do it for me. I'm a genius!
