Put simply, Kramer is King of the Kitchen Knife. As such, Bob Kramer has seen the knife from every angle-as a chef, a professional knife sharpener, and a Master Bladesmith. Although he is most widely recognized for his blades, Bob is also an expert on sharpening. In that spirit, he has collaborated with Zwilling to create the Kramer by Zwilling sharpening collection. In order to maximize the performance of any knife, it is very important that the edge be properly cared for. Retooling your knives' edges by hand may seem daunting to a beginner, but with Kramer's help many describe the experience as relaxing and gratifying. Keeping your blades sharp not only makes the cook's most important tool easier to use, sharpening makes knives safer. Used for centuries in barbershops, the stropping block is the best way to finish the edge of a knife or razor. A stropping block maintains the knife's edge between sharpening making it a useful and convenient tool to have around.
