Masamoto


Masamoto KK Series Kasumi White Steel No.2 Usuba (165mm to 225mm, 5 sizes)

Availability: Normally ships within 1 to 2 days


The Masamoto KK Series is Masamoto’s most affordable range of hand-made Japanese traditional-style Kasumi knives, however, they maintain the high standards of craftsmanship, product quality and cutting performance that Masamoto are famous for.

Masamoto KK Series Knife uses a blade core of Hitachi White Steel No.2 (Shiro-ko #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, therefore it can be used to create very sharp edges with good edge retention, which are still easy to sharpen.

 This knife is fitted with a traditional Japanese ‘D-shaped’ magnolia wood handle with a water buffalo horn ferrule / collar. This knife also includes a matching magnolia wood Saya (Sheath) for safekeeping.

The Usuba is ideal for cutting vegetables and fruits which are served raw, because the thin and sharp blade produces cut surfaces with very little cell damage, and this minimizes the discoloration and change in flavor often caused by oxidation. The versatile middle section of the blade can be used for thinly slicing vegetables and also for performing the specialized Katsuramuki ("Rotary peeling”) technique.

Notice about White and Marble Colored Water Buffalo Horn Ferrules for Masamoto Knives:

Unfortunately, Masamoto and most other Japanese knife makers have recently been struggling to source Wa handles with White or Marble colored Water Buffalo Horn Ferrules, which are becoming very scarce.

Due to these unfortunate circumstances, Masamoto cannot guarantee that they will be able to supply your knife with a White or Marble colored Horn Ferrule. Both we and Masamoto will do our best to supply your chosen color of ferrule, but it is very likely that Masamoto will only be able to supply a knife with a Black colored Ferrule.

We actually recommend the simple, stylish solid Black colored Ferrules because, over many years, numerous Wa Handle Craftsmen, professional Japanese Food Chefs and Experienced Knife Users have found these Black Horn Ferrules are stronger and more durable than White colored Ferrules and Marble colored Ferrules.

If you order a Masamoto knife with a Marble or White 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, but 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.

 

Important

This is the Carbon steel blade kitchen knife that can get rust and discolor easily, and requires extra care and attention to prevent rust.

  • Please do not put the knife in the dishwasher machine for cleaning.
  • Please do not leave the knife in water or wet condition for a long time.
  • After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes. Please apply Tsubaki oil on the blade and keep it in a 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.

    My first single bevel edge knife

    My fist use was little strange, because i haven't much experience in single bevel edge knives. But more that i use this beauty, that i like this heavy blade gliding just with the weight from itself into the vegetables. The rounded tip helps for gently rocking rolling chop or drag cuts. It's a must have.
