Kaishin "Thin Series" Aogami Super Gyuto
Pickup currently unavailable
This "thin series" wa-gyuto is a "laser" knife, hand-forged, handcrafted and hand-sharpened by a team of traditional artisans and craftsmen, using Aogami Super core steel, heat-treated to 64 HRC for extraordinary edge retention. The grind is quite smooth, with good thinness behind-the-edge and quality sharpening matching the price range of this series. The polish is done to a higher standard than most other knives of this cost, so the knife is very enjoyable to use. More importantly, Kaishin's magnolia wood handle comes with a blonde/marble buffalo horn kuchiwa, something less seen in knives of this budget range. Overall this is a knife of superb value for money.
Premium Handle Option: For a premium look, go for Sugi Fuki-urushi handle which is made by experienced Japanese urushi artisans with the finest sugi wood of Japan. Paired with the best blonde buffalo horn, this handle takes many hours to make by hand with the skilled labor of repeatedly applying lacquer with a cotton cloth to showcase the beautiful grains of Sugi wood. It is supplied in very limited quantity.

About Kaishin 魁心 / Nakamura Hamono Kogei 中村刃物工芸

Aogami Super (Blue Super) steel is considered the most superior Japanese high carbon steel for knife making. It is not stainless, therefore you must wipe your knife dry after each use, in particular the core steel not covered by the stainless cladding. Patina will develop over time, which will appear as “discoloration” on the cutting edge, but that is the nature of carbon steel - not a defect. The stainless cladding covers a large part of the blade, making maintenance easier but still preserving the cutting and sharpening pleasure of the Aogami Super core. Avoid cutting into bones, frozen foods, hard fruit pits.
Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.
We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
Ordering, Shipping, Customer Service… all amazing.
The knife is beautiful and performs like a dream. I ordered the Sugi Fuki-Urushi model, and handle is more beautiful in person than in the photos.
I remain conflicted because I could swear this knife has moderate issue on the tail portion of the blade. When I brought this up to customer service, they were amazingly quick to respond and assured me that my knife was not defective, however, myself and my fellow chefs all say customer service is wrong.
The edge is not cut through the full length of the blade. There’s a tiny portion left unbeveled. Burrfection’s support said this is artistic, but it’s annoying when you’re sharpening on a stone. I’ll have to remove the material myself so the edge can be maintained like every other Japanese knife you buy.
Overall 5 Stars - and some time on a stone.
