Masamoto KS Series SW-4324 Sweden Stainless Steel Wa Slicer 240mm (9.4 inch)

Availability: Normally ships within 1 to 2 days

The KS Series is Masamoto’s range of high-grade 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.

This Masamoto KS Series Wa Slicer knife uses Sweden Stainless Steel which is well known for its purity and fine grain structure, and makes similar high cutting performance as the Carbon steel knives.  

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 long, narrow blade of slicer is particularly useful for slicing meat, boneless fish, roast beef and ham. The long blade allows the meat or fish to be cut in one single drawing motion, from heel to tip.

This knife comes with 50/50 double bevel edge geometry for both right and left handed use.

For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left hander can use the knives that have double bevel edge sharpened 50/50 without problems.

We believe quality and performance of Japanese knives are best in the world and hope you enjoy fine craftsmanship and spirits from your new knife. With proper cares, every Japanese knife can be your special cooking partner for long time.

  • After using, please hand wash it and wipe it clean and dry with soft clothes. (Includes bolster and handle part)
  • This is an extremely sharp knife. Please use special cares in using and storing it.
  • Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.
  • Please do not use it to cut bone or frozen foods, hard foods such as lobster and crab which have hard surface.
  • We recommend re-sharpening the knife using Japanese whetstones, when it gets dull.
