There was nothing cooler growing up than watching an infomercial involving a maniac slicing through shoes, cans, and even tomatoes with ease. We have no idea what happened to that guy, but at least there's The Ultimate Edge, a company that makes premium grade, state-of-the-art Diamond Honing Steels for giving your blades the sharpest of edges. The 10" Gourmet model, which simultaneously hones and realigns edges, is made from microcrystalline diamonds bonded with nickel to a lightweight oval steel shaft, resulting in the ultimate honing tool for any knife collection.
