Mizuno Tanrenjo Akitada Hon Kasumi Series is Mizuno Tanrenjo’s range of high-grade Shiro-ko #2 (White steel No.2) Hon Kasumi Japanese traditional-style knives.
Mizuno Tanrenjo Akitada Hon Kasumi Series knife is completely hand sharpened, polished and finished by especially skilled artisans, which results in extra edge sharpness and a more refined level of finish.
Its blade is made with soft iron and Hitachi Shirogami #2 (White Steel No.2) which is heat-treated to HRc. 62-63. Shirogami #2 is a high carbon Japanese steel that is renowned for its purity and is easy to sharpen to a very fine edge that can also retain its sharpness for a long time.
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 Marbled Water Buffalo Horn Ferrules for Mizuno Tanrenjo Knives
Unfortunately, Mizuno Tanrenjo and most other knife makers are now struggling to find the raw materials to make White or Marbled Water Buffalo Horn Ferrules for their knife handles.
Due to these difficult and unfortunate circumstances, we regret to inform our customers that Mizuno Tanrenjo is no longer able to accept requests for a specific color of Water Buffalo Horn Ferrule. However, we firmly believe in the high quality and craftsmanship of Mizuno Tanrenjo’s traditionally-forged Japanese knives - They are one of the most well-respected producers of traditionally-forged Japanese knives - and we highly recommend them!
Thank you very much for your understanding and attention.

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). We try to keep the left handed versions in stock, but once sold out, it may take 30 to 45 days for delivery. 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 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 Carbon steel blade kitchen knife that can get rust and discolor easily, and requires extra care and attention to prevent rust.
Perfect balance and feel. Cuts paper thin, transparent vegetable slices. Saya fits beautifully.
