Milt gave me this jar opener for Christmas...and it works very well.
I wanted to let y'all know about it... cost $19.97 and Wal-mart carries it. If your Wal-mart doesn't have it, go to the Wal-mart website...and it will be shipped free of charge to you at your store.

We also have the One Touch Can opener and it's a goody too!
Doesn't take up much room, and so handy to have.
Happy RVing!
