The all new Konosuke HH Stainless. HH stands for High Hardness and we've asked Konsosuke to harden these knives to HRC61 and the result is a marked improvement in edge holding ability along with excellent stainless protection. The blade measures 240mm and uses comes with a nice ho wood octagonal handle and buffalo horn ferrule. The spine is rounded and this knife is very thin and light. Weight is just 124 grams. Spine thickness is 2.3mm. The fit and finish on these knives is excellent.
