The KS Series is Masamoto’s range of high-grade Sweden Stainless Steel Japanese traditional-style knife.

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.

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


This is the Stainless steel blade kitchen knife that has a good rust resistance for easy maintenance. However, it may get rust, if kept in wet condition.

  • Please do not put the knife in the dishwasher machine for cleaning.
  • Please do not leave the knife in water or wet condition for long time.
  • After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes, and keep it in dry place.
  • 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, any hard shell foods such as lobster and crab.
  • We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.

    This knife

    This knife, Ladies and Gentleman, is pure joy to use. Perfectly manufactured (rounded edges, ...), lightweight, good balance, good sharpness, and due to the blade geometry, it cuts through everything like a ... you know ;) Originally, I wanted to buy the White Steel-Version, but that is not available at the moment, so I went with the stainless Version - and I am not disappointed! I highly recommend this knife! (In the second Screenshot you see the Masamoto KS Petty 165mm and the Gyuto 210mm)
