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.

    Stainless Masamoto KS

    I bought the 240mm (about 10 inches) stainless version of this knife a little over a year ago (2/25/2019) and have been using this knife on/off since then. This is my first high-end Japanese knife. I first heard of this knife from Burrfection (Ryky's YouTube Channel) and it's certainly a high quality knife as mentioned on his channel. I also find stainless knives more appealing to home-cooks and amateur chefs like myself (less maintenance). Overall, cutting with this knife is great for bulk food preparation (softer foods like spring onions), especially when you have a lot of things to cut through. However, I probably would not recommend such a fine and big knife like this one for people who want to get into Japanese knives due to the following reasons: #1 for most people who don't have a ton of cash lying around, this knife will NOT be your ****** or workhorse knife #2 it's a very light and delicate knife and I still find it difficult to use on harder foods like sweet potatoes (I don't recommend using them on sweet potatoes esp since sweet potatoes leak a sticky substance which sticks to the knife). #3 because it's such an expensive and delicate knife, for most people, scratching this beauty would probably make you go OCD and try to polish off scratches for days. That being said, once you get over that fact that it's OK to scratch the knife here and there, it becomes a fantastic knife to use for softer, bulk food preparation. Another note, please do not use anything other than the soft sponges to clean this knife. I ******* up the first time when washing this knife and used the backside of the sponge to clean off difficult stains... BAD IDEA.
