Tojiro Supreme knives, are insanely sharp. These knives are made out of the finest Damascus steel wrapped around a VG-10 core to provide a very hard cutting edge (Rockwell 60-62). The handles are made from a hollow stainless steel that is comfortable to use. There is also a special die cast bolster welded onto the handle of the knives, which provides a smooth touch and comfortable grip. The overall knife is as sharp as you could possibly imagine, but it has the weight and presence of a European knife. Always wash your knives by hand, dry thoroughly and never put them in a dishwasher. All Tojiro knives are covered by the manufacturers guarantee against faults and defects. Knives should be stored in a block or other protective case to protect the blades and always kept out of reach of children. Knives cannot be sold to any person under the age of 18.
