The Shun Classic 6-Inch Serrated Utility Knife features 16 layers of high-carbon stainless steel pounded to 3/1000th of an inch and clad on each side of a VG10 super steel core, producing a 33-layer, rust-free Damascus pattern. This combination of materials gives Shun Classic knives strength, stain resistance, and incredible cutting performance. With the beauty of genuine wood, the black PakkaWood handle is made by fusing layers of birch with a durable, waterproof resin. All Shun knives in the Classic series also feature the uniquely stable D-shape handle design that rests precisely in the curve of your fingers. The asymmetrical bolster is ground out more on the right side to provide proper finger placement and an easy, secure grip. The knife is balanced perfectly, with the pivot point just ahead of where the handle sweeps out of the blade. Shun Knives are technically dishwasher safe, however, as with any lifetime investment, it's important to take the best care possible in order to prolong the life of your knife. For multiple reasons, Shun does not advise putting knives in the dishwasher. Hand-washing is recommended. Shun Knives are hand-made in Seki City Japan, the ancient home of samurai swords. NSF approved. Limited lifetime warranty.
