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.
The single bevel edged Kiritsuke is a versatile knife that can be used to perform some of the tasks usually done by the Yanagiba and Usuba. The heel section of the knife is virtually flat and can be used just like an Usuba.
Notice about White and Marble Colored Water Buffalo Horn Ferrules for Masamoto Knives:
For several years, Masamoto and most other Japanese knife makers have unfortunately been struggling to source Wa handles with White or Marble colored Water Buffalo Horn Ferrules, which are becoming very scarce.
Under these difficult circumstances, both we and Masamoto have done our best to satisfy customers who have requested knives with White Ferrules or Marble colored Ferrules. However, to cover increased costs, Masamoto will now require an extra US$13 when you request a knife with either a White or a Marble colored Ferrule. Please note that even if you request a Marble colored Ferrule, there is still a possibility that Masamoto will only be able to supply your knife with a White Ferrule. Similarly, even if you request a White Ferrule, Masamoto might only be able to supply your knife with a Marble colored Ferrule.
Although White and Marble colored Ferrules have an appealing, distinctive appearance, we actually recommend the simple, stylish solid Black Horn Ferrules because many years of expert experience (Including numerous Wa Handle Craftsmen, professional Japanese Food Chefs and Experienced Knife Users) suggests that Black Horn Ferrules are stronger and more durable than White or Marble colored Horn Ferrules.
If you order a Masamoto knife with a White or Marble colored Horn Ferrule and Masamoto cannot fulfil your request, we will inform you by Email and ask if you are willing to accept a Black colored Water Buffalo Horn Ferrule instead. We apologize for this inconvenience, however, no matter the color of the ferrule, we are confident that you will enjoy your Masamoto knife.

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 and production is very very limited.)
If the left-handed version knife is being out of stock in Masamoto inventory, it often requires very long delivery time. 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.
This is the Carbon steel blade kitchen knife that can get rust and discolor easily, and requires extra care and attention to prevent rust.
I’m Japanese and I have 25 years experience on sushi and this knife is exactly what I was looking for! It has the combination of a Yanagi and a Usuba in one single knife. I will tell this though, to perform both jobs with any flaw, you must have experience because it’s a blend, sometimes it can lack on some small jobs, for instance, to perform netas or sashimi cuts, you might feel it’s to wide and short, and for cutting veggies, you might feel that it’s too curvy to finish the cut. Things like that, you need to be able to fix using your experience to have its full performance.
Great fit and finish on this knife. A little more curve on the belly than I expected but still really pleased with this purchase
Like butter. Thank you Japanese Chef Knife! Such a beautiful knife
Item arrived super quickly and super sharp out of the box. Service was amazing.
If you like to cut very thin, almost transparent meat or fish fillets that melt in the mouth, this knife is perfect. It is a really beautiful and well finished knife. I understand why Masamoto is a brand so appreciated by the great Japanese chefs. My order came on Christmas Day. It was a very nice gift that I gave to myself. And as usual the service was excellent! I highly recommend Japanese Chefs Knives.com for lovers of beautiful Japanese knives. I have never been disappointed. Thank you for all !
