The Kohetsu AS brand is a great introduction to Japanese carbon steel. It is relatively easy to keep sharp with minimal reactivity. We make these knives with the simple aim of providing great performance at an attractive and affordable price. Made exclusively for CKTG by a leading blacksmith in Japan, the Kohetsu AS line of blades are thin, light, and strong.
We have specified an HRC rating of 64 to ensure a high level of edge retention and a simple maintenance requirement. This carbon steel core is reinforced with the addition of a stainless steel cladding. Naturally, the exposed carbon steel will patina with use but this oxidation only serves to enhance the look and protection of the cutting edge.
The grinds are very thin on this knife, with good convex shape for reduced food sticking. It has a nice progressive grind which Mr. Tsukahara biases more on the right side than the left. He also feathers and thins out the tip for great cutting performance. Despite the biased edge geometry, the knife will work well for left- and right-handed users.
We have made this knife available with a lovely custom handle created by one of our highly skilled woodworkers.
