The Kuhn Rikon Auto Safety Lid Lifter is a can opener designed for use by individuals with arthritis or fine motor, grasping, or upper extremity disabilities. This one-handled opener automatically locks on when placed on the can lid. When the knob is turned, the cutter removes the top portion of the lid just below the rim of the can, and the lid gripper lifts the lid off completely. This opener leaves no sharp edges and the cutting blade never touches the food. This opener can be hand washed. DIMENSIONS: 7.5 inches long. COLOR: Red, blue, or black.
