The Swing-A-Way Can Opener can be instantly taken off the wall for drawer storage, or swung flat to the wall, or left in the ready-to-go mode. With the wall of your kitchen adding stability, it opens cans with ease. A tag-along magnet holds onto the lid of the can. No more hunting for the damn can opener. No more struggle for leverage. A great gift, by the way to anyone with a strand of silver in their hair! Best attached to a smooth wooden surface. Screws are included. Precision steel gears are factory lubricated. Not made to be immersed in water. Best cleaned occasionally with a small brush and towel-dried.
