The Akitada Ao Hagane DX Series is the highest-grade of knives among Mizuno Tanrenjo large selections and is made using Hitachi Aogami #1 (Blue Steel No1; HRc. 62-63). Blue Steel No.1 Wa-Bocho (Japanese traditional-style knives) are rarely seen because the high Carbon content (1.30-1.40%) of the steel makes it difficult to work with. Blue Steel No.1 also contains greater amounts of Chromium (0.30 -0.50%) and Tungsten / Wolfram (1.50- 2.00%) than Blue Steel No.2, which form hard carbides in the steel and thus improve edge retention.
Mizuno Tanrenjo Ao Hagane DX knife is handcrafted and hand sharpened using traditional methods by Mizuno’s highly experienced and talented craftsmen and receive the utmost attention during each stage of production to ensure that no compromises are made.
Master Mizuno recommends Ao Hagane DX Knife with confidence due to the outstanding cutting performance, which equal to that of Honyaki knives.
This 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.
Yanagiba knives are primarily used to slice boneless fish fillets for Sashimi and Sushi dishes, but they can also be used to fillet small to medium-sized fish and are often used for skinning fish. The narrow blade and relatively acute edge angle of the Yanagiba are features which greatly reduce the effort required to cut through ingredients. As with the Sujihiki, the long blade allows the fish to be cut in one single drawing motion, from heel to tip.
The combination of cutting technique, acute blade angle, and sharp edge result in very little cellular damage in the cut surface. This is particularly important for dishes where the fish is eaten raw, because it helps to preserve the original flavor and texture of the fish.
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.
- 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.

- We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.
