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.
Yanagiba knives are primarily used to slice boneless fish fillets for Sashimi and Sushi dishes, but they can also be used to fillet small to medium-sized fish and are often used for skinning fish. The narrow blade and relatively acute edge angle of the Yanagiba are features, which greatly reduce the effort required to cut through ingredients. As with the Sujihiki, the long blade allows the fish to be cut in one single drawing motion, from heel to tip.
The combination of cutting technique, acute blade angle, and sharp edge result in very little cellular damage in the cut surface. This is particularly important for dishes where the fish is eaten raw, because it helps to preserve the original flavor and texture of the fish.

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.
We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy the fine craftsmanship and their sharp edge of your new knife. With proper cares, every Japanese knife should be your special cooking partner for a long time.
