Query: Just what I was looking for.

I've been trying other types of jar openers for years--the rubber pad ones and the ones that squeeze around the top that look sort of like pliers--and also I've tried the hot water and tapping the lid with a knife, and never was very satisfied. When I was growing up we had one something like this one, and I have never seen one since. As soon as I saw it, I wanted it. The benefits: works for any size jar and gets a good grip on the lid. Yes you still need some force but not as much as you would need without it, and it doesn't slip. I have small hands so I have problems getting a good grip on wide lids and this solves that problem which most of the other methods do not. I got one for my mother too, and she likes it too.
