Kohetsu is our in-house brand of knives made to our specifications by a variety of blacksmiths using some of the best traditional and leading edge steels.
The alloy used is for this lovely honesuki is HAP40. This semi-stainless steel is forged to a very hard 65 Rockwell. HAP40 is one of the hardest steels available for knife-making and it provides fantastic edge retention. It also polishes to a razor’s 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.
This HAP40 Western Honesuki is a poultry boning knife. The shape is specific to that task: pointed tip, triangle shape, and fairly thick and robust. This example is double bevel as opposed to many others that are single bevel, and thus more difficult to sharpen. Do remember that they are boning knives and are not intended to cleave bones like a cleaver or deba.
The blade is coupled to a fine looking western style handle with scales made from rosewood and attached with 3 stainless rivets.Brand: Kohetsu

5 Star Steel, 4 Star HandlePosted By: Charles Binger

Would I buy this again? In a second. In fact the only reason I'm on the site today is to buy a Hap 40 Nakiri. HAP 40 is everthing good you've ever read about it, and the grind of this blade is great. HAP 40 tests (by Larrin) show it having about 85% of the edge retention of ZDP-189 and about 50% tougher. I can't wait to try Magna Cut steel (came out 4/21) with 70+% of ZDP's edge retention and 2 to 4 times it's toughness (depending on heat treat). CKTG checked all the boxes with this knife, especially the Hap 40 steel selection. I have a furniture hobby, so I'm picky about wood. The handle has a great shape and feel. The finish and sizing was off. Someone filed down the tang in one area after the knife was assembled, which left scratches on the tang and the wood finish. Nothing major but it shows some. Someone sanded the wood in a couple spots after it was stained (but b4 final finish coats) to bring its size in line with the tang and touched up the stain badly which leaves the handle a little 2 toned. As I said, I'd buy again. The steelwork is perfect and I didn't expect perfect fit and finish on the wood.

Great for piecing out whole birds - raw and cooked. We raise our own pastured poultry, so lots of opportunities to use this beautiful and effective knife. Feels great in the hand and gets the job done. A pleasure to use! Good online shopping experience and shipping was quick.
