Smooth Edge Can Opener - The most basic principle of the manual can opener is to use a gear to drive a sharp blade to make a circle to open the can lid. So we improved the precision of the gear and used high carbon steel blades instead of ordinary blades,the razor-sharp blade and precision gears work perfectly together to cut the lid smoothly with every revolution of the blade. so don't worry about getting scratched by the burred edge of the can when scooping food from the can. Improvement of Manual Can Opener - We use Eco-friendly rubber in the handle and turn knob, which greatly improves the hand-held comfort of the manual can opener and avoids hand slipping when opening the can even if your hand is oiled. The knob withincreased height and finger contact surface makes the hand more effortless when opening the can, and the knob can be twisted 360in both directions, which is a great gift for the elderly and arthritis. Focus on Safe Can Opener Tools - We've attached a strong suction magnet to the bottom of the can opener, and added a strong fluted base to the magnet to prevent the magnet from falling off. Once the lid has been cut by the blade, just use the magnet topull the lid up, which keeps your hand away from the smooth (and possibly sharp) edges of the lid and keeps food clean.
