My glove size is women's large (or men's medium), and I have fairly strong hands but carpal tunnel surgery in my nondominant hand has resulted in some degree of weakening of the jar-holding hand. Lately I discovered a few condiments that I like a lot, but their lids are over 3" in diameter. I have a hard time opening them with my standard methods:
the opener that's a round sheet of rubber, holding the jar upside down and slamming the lid flat onto the counter, putting the upside-down jar in a half inch of very hot water, banging a knife handle around the edge of the lid. I succeed EVENTUALLY, but it's really tiresome.
Previous jar opener threads are over 6 yrs old so those models may have been replaced by others. Any opinions on the current crop of jar openers' effectiveness for larger lids? Merci buttercups!
