Whether youre slicing meat, dicing vegetables, or carving the Sunday Roast, a sharp blade makes cutting effortless. AnySharp restores a super sharp cutting edge to blunt knife blades that have dulled with use. The AnySharp uses tungsten carbide technology to extend the life of almost any knife. AnySharp works on virtually any knife, including expensive hardened steel knives. AnySharp Pro even works with serrated blades* (like bread knives and hunting knives), making it unlike any knife sharpener, steel or sharpening stone youve ever used. *Not very fine toothed serrated knives. The optimum angle to sharpen a good quality steel knife is 20 degrees. AnySharp is pre-set at 20 degrees to give an optimum edge every time. Getting a consistent angle with a sharpening stone is a skilled job, but AnySharp allows anyone to get professional results without any training at all. The AnySharps safety feature is its PowerGrip suction cup base, which attaches securely to any smooth surface or worktop without the need for any tools. Once its attached you can sharpen any knife safely hands free. When your whole knife has been run through, your knife edge may touch as it exits the sharpening tools. The AnySharp has a long-lasting polymer guiding top that is softer than metal, and therefore wont damage the metal edge, making it safe for your knives too. With a totally blunt knife, AnySharp will hone it to an optimal angle, and remove excess metal rapidly the first time you use it. AnySharp does not work well with heavy strokes or too much pressure. Please use only light pressure.
