AnySharp make the bold claim that this is the World’s Best Knife Sharpener.
Whether you’re slicing meat, cutting fabrics, or mowing the lawn, you’ll want your blades to be at their sharpest. Regular use of even the highest quality blades will dull their edge, resulting in a loss of accuracy or the need for more effort when cutting.
The AnySharp Knife Sharpener uses new, patented knife sharpener technology, making it superior to any knife sharpening steel or stone. Unlike other knife sharpeners, AnySharp is totally safe to use, because your hands are always away from the blade.
The PowerGrip suction cup means you can attach the AnySharp Knife Sharpener to almost any surface, horizontal or vertical, without the need for tools. And since it is so small and light, it can be easily tidied away in a drawer, cupboard, or tool box when not needed.
