Very sharp cutting wheel. Sharp spherical discs cut cans effortlessly for smooth, child-safe edges. The safe cut and twist design leaves a smooth edge on the can and lid. Simply place the smooth-edged lid back on the box to store uneaten food. Extremely easy to use The ergonomic twist handle makes opening cans in seconds a reality. The large, thick, non-slip rotary knob allows for easy operation and gives you a comfortable grip. The non-slip soft silicone handle gives you the perfect leverage and is easy to store. Side Cut Safety Can Opener The can opener cuts large, small, round or oval cans on the side, so there is no cross contamination because the blades do not never touch the food in the box. The alignment loop allows you to quickly align the can opener to the lid and lets you see when the can opener has completed the 360 degree cut. Easy to clean: Since the cutting discs do not touch the food in the box, you only need to rinse it under running water and then let it dry. The high quality stainless steel disc never rusts. Made from high quality materials: Industrial grade silicone and plastic are used in the manufacturing process to ensure a lifetime of use
