Kohetsu HAP40 Western Petty 120mm

Kohetsu is our exclusive line of kitchen knives created to offer cooks of all kinds a blade made with excellent materials at a very reasonable price. Kohetsu HAP40 series knives are a new addition to the label that will appeal to the performance customer demanding unmatched edge retention.

HAP40 is a semi-stainless, powdered high-speed steel (HSS) that takes and holds an edge better than any other steel available on our site. HAP40 is fine-grained enough to sharpen very well and rates 64-68 on the Rockwell Hardness Test (HRC)—even harder than the traditional carbon steels used for knives. We have specified hardness of 65-66 HRC for our blades. Unlike other HSS steels, they can be relatively easily sharpened on normal Waterstones, if not quite as quickly as traditional carbon steels. We think HAP40 holds the potential to become one of the best steels on the market for the production of high-quality, high-durability kitchen knives.

The finely ground blade of this lovely 120mm petty is welded to a stainless steel bolster, and a Western-style mahogany handle is attached with 3 stainless rivets.

Please note, the knife sharpener intentionally thins the edges of these knives to make them perform better, especially on the tip area. Often times you will see a hazy/cloudy scratch pattern as a result. This is not a defect. Please look at the 4th photo on this page to see it.
