Wusthof Diamond Knife Sharpener


A blunt knife is a useless knife — bring yours back to life with this outstanding quality diamond steel from Wusthof. The finely ground diamonds that coat the rod on this sharpening steel will hone and sharpen a blade extremely quickly and effectively. This diamond steel from Wusthof is the right tool to reach for when you need to achieve the best results in the least amount of time. The highly abrasive diamonds mean that one stroke of a knife against this steel is equivalent to around eight strokes against a conventional metal steel. The diamonds are extremely fine which means that you can achieve a razor sharp edge with ease. We recommend that you wet the steel with water before use. The water lubricates the passage of the knife across the steel which leads to an even finer, sharper cutting edge as well as reducing wear and tear on the diamond steel itself. Diamond steels are very popular with professional chefs who always need the best results in a hurry. This top quality steel from Wusthof is a great, long term investment.
