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.

    Masamoto SW 240mm

    Have owned this knife for a while now and I am very happy with its performance. I have a few KS white steel knives and tried out the VG gyuto. I was very curious about the SW. It handles well, takes on a very fine edge and overall a very beautiful knife

    A masterful piece of kitchen weaponry

    I couldnt be happier with this knife. I bought the KS Gyuto 270mm and have found it be beautifully weighted and easy to maintain. I cannot recommend this knife enough.

    Excellent product and service

    A worthy (and presumably easier to maintain) substitute for the White Steel No. 2 version, which remains hard to source. Customer service is first rate.

    True Masterpiece.

    Hi, I'm a professional chef who bought this KS almost an year ago and now, after intensive use, i can finally review this product. Is a masterpiece. The legendary profile of the KS really shine, nice flat spot toward the heel a gentle belly in the mddle and a super thin tip ( you really need to pay attention to it ) for detail works makes this knife a nice all arounder for rocking and push cutting. As far as AEB-L goes is a nice steel, easy to sharpen but the edge retention is kinda borderline, i use it on poly board and have to touch it with my CHOSERA 3000 twice a week to mantain a nice sharp edge, i whish it was a little bit harder just for pro use, if you are an home cook there should be no problem. Overall it's a piece of art: the balance point, the construction and the grind are just outstanding. Now i'm leaning towards R2 steel knives but the KS holds firmly a spot in my knife bag and i keep on using it almost every day. 4 stars just for the edge retention. i forgot to mention that the shipping and the customer care were top notch. Matt.

    Masamoto KS Stainless SW Wa-Gyuto

    A great knife to work with! Extremely sharp and very light. The D shape handle is one of its advantages if you are using it for many many hours. Definitely one of my best knives!
