We have created the Kohetsu HAP40 Western line of knives for chefs of all kinds, be they amateur or professional. The blades are made from one of our very favorite steels, HAP40 powdered high speed steel. This amazing alloy has been developed by Hitachi Metals and is especially liked by many makers of fine kitchen utensils. The knife protector fits much better than a saya since this is a thin knife.
HAP40 is fine-grained enough to sharpen very well and can be hardened to 64-68 HRC, harder than the traditional carbon steels used for knives. Contrary to other HSS steels, it can be relatively easily sharpened on normal stones, if not quite as easily as traditional steels. It also polishes to a razor-sharp edge fairly easily, especially considering its hardness. It holds an edge better than almost anything else we sell. It is a semi-stainless alloy which is then clad in a full stainless steel outer layer, so it's also easy to care for.
There is something quite intriguing about the shape of a bunka
. The combination of the reverse tanto-style tip and short, tall blade lend the knife a very purposeful look. These knives are gaining in popularity recently due to their do-it-all abilities. They are adept at cutting, slicing, and chopping, while the tip affords them the ability to take on smaller ingredients and get into tight spaces. They are a good choice for making garnishes and undertaking detail work of all kinds.
