CoSay Kohetsu HAP40 santoku (universal knife), octagonal, AHP-S18J
CoSay Kohetsu HAP40 santoku,
Double-sided cut and laminated (sanmai) blade made of stainless steel with a core of Japanese HAP40 steel. The blade is extremely thin and manually ground and has no thickening, making grinding on Japanese water stones very easy.
HAP40 is known as one of the hardest semi-stainless steels currently available. The steel contains very large quantities of alloying material such as Cobalt, Molybdenum, Vanadium and Tungsten. HAP40 is extremely hard and durable, but more sensitive to corrosion and breaking out of pieces than, for example, SG2, VG-10, SLD or SKD11. In addition, HAP40 is difficult to sharpen and therefore difficult to process by manufacturers, so it is very difficult to find kitchen knives made with this steel. Thanks to our unique collaboration with a well-known knife smith (who makes the famous Kohetsu knives, among others) in Japan, we can now offer this HAP40 line.
