This is a black handheld manual can opener from KitchenDao with a built-in magnet. The magnet lifts the lid off once the can has been opened, so you do not need to touch the cut edge with your fingers, and it also lets the opener be stored on the fridge door. KitchenDao makes several can openers, some with replaceable blades and large turning knobs for people with weak hands, and we could not confirm which version this is, so blade type and dimensions are not listed here. It is a simple, sturdy kitchen tool for home, caravan or camp kitchen use.
