This is a prototype tool I designed for someone like me that has arthritis and cannot grip a jar lid very good any more.
I was originally going to make it with the oval hole for your hand instead of having to “grip” a handle and I was going to make the end like a basin wrench with a serrated jaw on a hinge that wrapped around the lid. Then I saw one similar to this for sale with teeth on one side and a flat top so it sat on the lid. So I changed the design a bit. I used two pieces of pine from my cut off bin and milled the slots to insert 2 pieces of hacksaw blade for the grippers. I did that while it was in halves so I could get it done accurately. Then I just glued the 2 pieces together and routed the edges a bit to make it user friendly. The blades slide in and will stay with a little epoxy. I can take them out now to try another blade. In trying it, I’d say it needs the coarsest blade I can find. This one is 32 teeth and it slips. I have the blades installed so one is pointing up and the other down so they both engage in right direction. You can flip it over to tighten, too.
The oval hole lets your whole hand do the twisting.
The pine is stained with Zar Z118 dark mahogany and finished with clear lacquer.
