Kasumi Knives - Kasumi Damascus Knives are madeare produced by Sumikama Cutlery in Japan, in Seki the traditional home of the ancient Japanese swordsmiths. Sumikama Cutlery specialises in producing knives from the most advanced materials with the most advanced manufacturing techniques. This series of Kasumi knives is referred to as the VG-10 Pro series. VG-10 knives are widely known as multilayered clad knives with a decorative pattern on the blade. The Pro knives are single ply knives with VG-10 "super steel" blades that range in thickness from 1.8 mm to 2.1 mm depending on the length of the knife. Compare this to approximately .3 mm to .5 mm of VG-10 in a multilayered clad knife. A single ply knife offers more stability in the blade, since you do not have multiple steels with different Rockwell hardness as you do with a multilayered knife. With Kasumi VG-10 Pro knives you get 4 times more "super steel" for a better price than clad knives. Kasumi Damascus Knives are used by celebrity chef James Martin - See them on his TV programmes.
