Kazan HAP40 Hammered Gyutou 240mm (9.4")

Chef's Knife

Kazan HAP40

We developed the Kazan line in partnership with a steel maker in Kansai, Japan.  HAP40 is a powdered steel blend featuring high levels of Vanadium, Molybdenum, Cobalt and Tungsten, resulting in a semi-stainless blade with exceptional edge retention.  Despite the incredible hardness of the blade, they are responsive to sharpening on whetstones.  

Kazan features a hammered tsuchime finish, which prevents food from sticking to the blade.  It's medium weight and has a comfortable gray wood handle.  The blade is hand sharpened on several stones for great out the box sharpness.  Kazan is made exclusively for Chubo.
