The Kohetsu HAP40
sujihiki is a lean, mean slicing machine. Sujihikis are slicing knives and we tend to sell them to people that do a lot of carving as well as to sushi line cooks that need a thin, great cutting knife. This one in particular is excellent at both tasks. Its blade is very nicely convexed and comes with a screaming sharp edge right out of the box. It is a very light knife and at 270mm is perfect for home use and pro kitchens with limited space. But make no mistake—it is certainly long enough for single-draw slicing and carving.
The steel used is HAP40 which is forged to a very hard 65 Rockwell. In layman’s terms, it is an insanely hard steel. HAP40 is one of the hardest steels available for knife-making and it provides amazing 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. If you're doing a lot of slicing work or want a sushi style knife with an easy to care for double bevel, this knife is ideal and almost nothing compares in this price range.
