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.Maker: Kohetsu

Pretty good knife... Voodoo Steel StunnerPosted By: Kurt Peeters - verified customer

I first purchased the 240 HAP40 Gyuto but needed a little friend for it. I looked at a bunch of different petty's in different size ranges but just couldn't say no to this guy. Even at a modest 120mm this thing can work. I love the flatter profile in the heel area for chopping scallions, shallots, garlic, etc. Another nice bonus in that my wife isn't afraid of the thing so she uses it as well. Again, great fit and finish with a tremendous steel. Thanks Mark!

14 years in professional kitchens, now a home cook. Blade is nicely ground and beautifully finished. Edge OOTB is 9/10, as good as you could expect from a production piece. Mild quality control issues with handle, choil, spine, bolster fit and finish. These were resolved with 20 minutes of
