Mizuno Tanrenjo

Mizuno Tanrenjo Akitada Honyaki Series White Steel Wa Santoku 180mm (7inch)

Availability: Normally ships within 3 to 6 days

Since ancient times, the Japanese Katana has been admired for its ability to take an extremely sharp edge and function without bending or breaking. Mizuno Tanrenjo’s Honyaki knives are being crafted using similar traditional methods to achieve the same functionality as the legendary Katana.

The inheritance of these traditional swordsmithing techniques allows Master Mizuno to bring out the maximum performance and beauty from the Hagane used to create these Honyaki Wa-Bocho masterpieces.

We are proud to introduce Mizuno Tanrenjo’s wonderful and beautiful Hamon layer of Honyaki Series (White Steel), which is heat-treated and to an incredible HRc. 64-65.

The tall blade and rounded nose / tip of the Santoku make it a versatile knife that is well suited to cutting meat, fish, or vegetables; Hence it’s name, which literally means “Three-purpose”. The Santoku is often recommended as a multi-purpose kitchen knife.

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.

  • 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. Please apply Tsubaki oil on the blade 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.

    Cute / Nimble

    I have used this knife exclusively for the last three days, and sharpened it at the end of every day. I enjoy how this knife feels on my water stones and how easily it saturates the mud with metal. It holds a great edge. The mirror polish finish allows a pleasant grace period for drying to knife before needing a bit of hand polish. It's a very classy knife, but also cute and nimble.

    Great knife but started turning quickly

    I love how sharp this knife is but it did begin to turn rather quickly. I only used a scrub brush with dish soap to clean it. So, I’m not sure what I did to make it turn.

    Comes with no cutting edge

    Comes with no cutting edge so might want to get it sharpened by JCK if want to use it right away.

    Amazing knife / Magnifique couteau c'est de l'art

    Magnifique couteau finition miroir avec un tranchant rasoir. Un bel objet d'art finalement. Excellente communication comme d'habitude et un service irréprochable. 5 étoiles sans aucun doute.
