Whether you live alone or just with roommates with weak wrists, a simple task like opening a jar may be an issue - one that's easily solved.
Forget banging jars with knives and twisting with fabric until your hands are red and raw. All you need is a simple bottle opener with a triangular point.
To begin, wedge the triangular point of the bottle opener under the rim of the jar. You may need to wiggle it a few times until it hits a grove. Push down on the handle of the bottle opener until you hear a "pop". Voila! The jar lid will now twist off easily.
