Rockingham Forge’s new professional sharpening whetstones will give you blades which are sharper, safer and easier to use than ever before. Available in single or combination stones with varying degrees of grit and coarseness, it’s time to embrace the number one recognised method of sharpening! The grit size or coarseness of a sharpening whetstone is indicated by numbers. The higher the number or GRIT, the finer the stone, the less steel it will cut through and the better it will polish the edge to a sharp bite. 240-1000 grit are coarse blocks, cutting steel more quickly and therefore best for damaged, chipped, rusty or blunt knives. 3000-8000 grit are honing or polishing stones, used to refine the edge of the blade, removing scratches and burr left from coarser stones and giving the blade a shiny, mirror finish. When using the whetstone, continue applying water whilst sharpening, making sure the stone remains wet. The water will react with particles in the stone to form an abrasive substance which enables the sharpening process.

The Rockingham Forge Knife Sharpening kit features all the components you need to restore kitchen knives from a blunt or chipped state to high levels of sharpness in no time! The set features a dual grit whetstone, with a 400-grit edge for restoring chipped and completely blunt knives, and a 1000-grit edge for honing dull blades. Using this set, you could take your damaged knives from a useless state back to chopping, slicing, and dicing quickly and easily. The whetstone is made of ceramic, which is easier to use and clean than conventional corundum stones, as well as being longer lasting. To make the sharpening stones as easy to use as possible, the set also includes an angle guide to help keep your knives at the optimal sharpening angle as well as a non-slip base, protective carry case, and sharpening stone leveller.

Rockingham Forge Ceramic Whetstones are an extensive range of knife sharpening tools, also known as waterstones, which will restore your blunt kitchen knives or hone already sharp edges in no time. This range is designed from ceramic rather than the conventional corundum used in other whetstone types, as it is longer lasting, more effective and much cleaner to use. The grit size or coarseness of a sharpening whetstone is indicated by numbers. The higher the number or GRIT, the finer the stone, the less steel it will cut through and the better it will polish the edge to a sharp bite. 240-1000 grit are coarse blocks, cutting steel more quickly and therefore best for damaged, chipped, rusty or blunt knives. 3000-8000 grit are honing or polishing stones, used to refine the edge of the blade, removing scratches and burr left from coarser stones and giving the blade a shiny, mirror finish. These stones are much harder than the traditional whetstones, so they wear a lot slower.
