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.

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.

    Mizuno Tanrenjo Akitada Hontanren Series White Steel Wa Santoku

    Gorgeous knife. I purchased this knife as a gift for a family member who loves to cook. This knife is beautifully crafted and arrived with an incredible edge that will be a breeze to maintain. I did pay for the additional sharpening and I am glad I did. Easily the nicest knife I have purchased and reasonably priced given the quality. Highest recommendation.

    Love it!

    This knife is very well made and is crazy sharp out of the box. The blade is incredibly reactive so be very careful! Don’t leave this knife sitting out for more than 5min after cutting something! Also the shipping was very fast! I am very happy with this purchase!
