The KS Series is Masamoto’s range of high-grade Shiro-ko #2 (White Steel No.2) Hon Kasumi Japanese traditional-style knife. When compared with the Kasumi knife-making process, the production of Hon Kasumi knife requires several extra steps be carried out during the forging, quenching, sharpening and finishing stages of production and requires a higher level of craftsmanship. Unlike the KK Series, the KS Series is completely hand sharpened, polished and finished by especially skilled and experienced craftsmen, which results in extra edge sharpness and a more refined level of finish.
Masamoto KS Series knife uses a blade core of Hitachi White Steel No.2 (HRc. 62-63), which is forge-welded with soft iron. White Steel No.2 is very pure and is capable of achieving a high hardness level without being overly brittle, so it can be used to create very sharp edges with good edge retention that are also easy to sharpen. It is perfect for professional users who like to keep their knives extra sharp.
Each knife is fitted with a traditional Japanese ‘D-shaped’ magnolia wood handle with a water buffalo horn ferrule / collar and also includes a matching magnolia wood Saya (Sheath) for safekeeping.
The single bevel edged Kiritsuke is a versatile knife that can be used to perform some of the tasks usually done by the Yanagiba and Usuba. The heel section of the knife is virtually flat and can be used just like an Usuba.

Japanese Traditional Style “Wa-Bocho” knives generally come with Single bevel edge for right handed use (the opposite side of blade is ground flat with slightly concaved shape). The reverse grinding left handed version is also available at 50% extra of regular price. (Sorry for much extra! Due to a small demand for the left handed version in Japan, it is costly to run a special small production from the beginning step). We try to keep the left handed versions in stock, but once sold out, it may take 30 to 45 days for delivery. Please contact us first for the availability at email.

This is the Carbon steel blade kitchen knife that can get rust and discolor easily, and requires extra care and attention to prevent rust.
I bought the 270mm version - it is an amazing piece of art. After unpacking, I've seen (and felt) immediately, this was the real deal, even more than I expected. Apart from being absolutely beautiful, it feels really good in the hand (D-shaped handle). It is quite blade-heavy and comes insanely sharp (I let JCK do the sharpening, since I was new at this and didn't have any stones yet). This knife, however, is not for the beginners - the steel is very hard and demands a proper cutting technique, otherwise it's chip-city. But that also means, that the edge retention is out of this world! All in all, I am very happy with this purchase (bought it over a year ago) and I can only recommend it.
This is exactly what I wanted. You won’t be disappointed.
Beautiful blade, incredible fit and finish! A dream to work with!
Excellent and personal service by JCK. A reliable and quick way to get top quality products from Japan. 10/10.
