These ultra sharp knives are forged from a High Carbon Steel. This steel assures the sharpness of the knife is surgical whilst being consummately easy to resharpen. They have been especially made for us by a long established factory in Seki city that produces a very quality knife for department stores and chain stores in Japan.
These blades will oxidise if left damp or wet and should be dried immediately after washing and oiled with a little vegetable oil or Tsubaki (Camelia oil available in the accessories section). These knives are very easy to sharpen on a KC100 Water Wheel, a diamond steel or a 1000 grit whetstone.
