A Swedish Cutting Board. Chops carrots, potatoes, celery, pots and pans and nooks and crannies. I open jars and cans, too. My left hand is everything; the right hand is DOA, unfortunately. There’s suction cups, four corners, and it’s difficult. Not to worry, pried with my left hand (the suction cups) and it washes with a paper towel. It adheres well.
Use the little vise-grip (the red sphere) for jars and cans. The cutting board are four suction cups. Press tightly on the vise-grip. Use the jar gripper pad. or a tea towel works. (Remember, leftly loosy and righty tighty, sometimes, I get confused for the left hand.)
