Incredibly Simple to Use; Kitchen knives in a typical home kitchen don't get an easy life Tossed into dishwashers, and slung away into kitchen drawers, knives can pick up minor dings and areas of micro corrosion. Other pull-through sharpeners, although fast and easy to use, can 'catch' on these small notches on the blade which may cause further damage. At the other end of the sharpening spectrum, methods such as whetstones and sharpening rods are gentler and can deal with minor blade damage. However, they also require a much higher level of skill and patience than the typical busy home chef has time for. Sharpening a single blunt knife properly with a whetstone can take 30 minutes or more. The; has been designed to combine the best features of each of these sharpening methods into one single device. The has the speed and ease of use of the traditional, single-stage pull-through sharpener. It also blends aspects from whetstone sharpening to protect your knives and makes sharpening gentler and more effective. The; first stage works on day-to-day nicks and imperfections on the blade edge, which allows for smooth and even sharpening on stage 2. The final stage removes any burs and polishes the blade for a brilliant finish. Stage 1 - Coarse Diamond Coated Rods This stage 'roughens' the knife edge to prepare the surface for sharpening. It also smooths any nicks and imperfections that could cause the blade to 'catch' during the sharpening stage Stage 2 - Hardened Tungsten Carbide Now simply pull the blade through slot 2's precision angled tungsten carbide plates to create the perfect sharpened 'V' edge on even the bluntest knife. Stage 3 - Fine Ceramic Stone Rods For final edge honing. It removes any burs and gently polishes the blade edges for a super sharp finish.
