One Touch™ Can Opener II needs no hands! Just place it on any can and it will “travel” around the lid, cutting the can open smoothly and neatly. There will be no sharp, jagged edges either since it cuts under the rim of the lid, not through the top. A handy built-in magnet holds lid off food, and provides for safe disposal. New and improved design has an easy-access battery chamber. Requires 2 AA batteries (not included).
