This 10-in Diamond Sharpening Steel has a diamond-honed surface to keep your Global knives razor sharp. The steel is carefully weighted and features the same distinct handle design as the knives. This Diamond Sharpening Steel is terrific for sharpening all your knives on a weekly or monthly basis, depending upon how often you use your knives. Loved by professional chefs around the world, Global knives are an excellent choice for the serious home cook. The thin and razor sharp Global blade allows the cook to cleanly slice through foods, preserving the integrity of the ingredient and maximizing its flavor. The majority of Global knives are ground to a straight point rather than the western style of beveling the edge. To balance their knives Global uses a hollow handle that is filled with just the right amount of sand to create the correct balance. The handle has its own unique darkened dimples for a non-slip grip. Because the knives are very light weight they reduce hand fatigue. Global knives have a smooth contour and seamless, all stainless construction that eliminates food and dirt traps. Global knifes are forged in Japan from CROMOVA 18 Stainless Steel, a blend of 18 percent chromium for good stain resistance plus molybdenum and vanadium which gives excellent edge retention.
