This is what happens when two very different skill sets come together and the result is greater than the sum of its parts. Kisuke Manaka hand-welds and forges each blade using ATS-34 stainless core steel in a traditional hon-warikomi (true insert) construction — a method that speaks to the man's decades of experience in Sanjo. On the other end, Xinguo, an emerging bladesmith from China who's been quietly building a serious reputation, takes over with finishing work that is frankly on another level.

If Xinguo's name rings a bell, it might be because he handled the sharpening on our last batch of Manaka ENN Damascus. His sharpening and polishing work is immaculate — on these blades, you won't find a single visible machining line. The edge comes out extremely straight, the choil and spine are polished and rounded to a degree that makes the knife genuinely comfortable to choke up on, and the deep tsuchime (hammered) texture across the blade face adds both visual character and food release. It's a high-polish, high-effort finish that you rarely see at any price point.

In the hand, these are hefty, no-nonsense workhorses. They run long, tall, and carry real weight — the kind of knives that feel planted on the board and power through dense roots and heavy prep without flinching. But despite the robust build, the cutting performance is surprisingly refined. ATS-34 is a well-proven stainless steel that holds an edge reliably and sharpens up without drama, making it a practical choice for cooks who want a knife that works as hard as they do.

The lineup covers pretty much the full range — gyuto, petty, chuka, santoku and more — so there's something here regardless of your preferred profile. These sit firmly in the high-budget category, but for a hand-forged Manaka with this level of finishing, the proposition is a compelling one. Collectors and enthusiasts who value the intersection of traditional Japanese forging and exceptional hand-finishing will find a lot to love here.

Pros Cons
  • Excellent performance
  • Great artistic
  • Highly collectable
  • Mirror polish can be hard to maintain
  • High budget

Kisuke Manaka

Kisuke Manaka Tanrenjo - The one-man crew from Sanjo (Est. 1872)

Kisuke Manaka is a 5th-generation blacksmith from Manaka Hamono, a workshop founded in 1872. Now based in Sanjo, Japan, Manaka-san operates as a true one-man workshop, handling every step of the process himself—from forging and forge-welding to sharpening.

He is especially known for making his own steel billets in-house, creating unique and often exotic Damascus patterns rarely seen in modern knife making. Blending over 150 years of tradition with complete independence, Kisuke Manaka’s knives are highly regarded for their craftsmanship, individuality, and performance.

Kisuke Manaka is a 5th-generation blacksmith from Manaka Hamono Tanrenjo, a historic workshop founded in 1872 in Saitama, Japan. With roots tracing back to traditional swordsmithing, the Manaka workshop has preserved classic forging techniques for over 150 years, forming the foundation of Manaka-san’s work today.

Unlike many makers, Kisuke Manaka operates as a true one-man workshop. He handles every step of the knife-making process himself—from forging and forge-welding to heat treatment and sharpening—ensuring complete control over quality and performance. His approach is deeply hands-on and independent, reflecting both traditional craftsmanship and personal innovation.

A defining feature of Manaka’s knives is his commitment to forging his own steel in-house. Rather than using pre-laminated materials, he forge-welds his own billets using the traditional warikomi method, even working with difficult materials such as stainless steel. This process allows him to create highly distinctive and often exotic Damascus patterns, each blade carrying a unique character that cannot be replicated by mass production.

Recently, Manaka-san relocated from Saitama to Sanjo—one of Japan’s most renowned knife-making regions—seeking to further refine his craft among other master artisans.

The result is a rare combination of heritage, individuality, and technical mastery. Kisuke Manaka knives are highly sought after for their fully handmade nature, unique aesthetics, and uncompromising craftsmanship.

“The new kid in Sanjo that has an old history behind. ”

Profile

Chuka (Cleaver)

Chinese Cleaver

The Chuka Bocho, or Chinese cleaver, is a large, versatile knife central to Chinese cooking, featuring a broad, rectangular blade. Beyond its primary functions of slicing, dicing, and chopping vegetables and meat, its wide blade also excels at scooping up prepared ingredients for easy transfer from cutting board to pan. Despite its formidable size, it is not intended for cutting through bone, but rather for precision tasks and handling both fine and heavy-duty chopping. Blade lengths typically range from 180mm to 220mm, offering a generous cutting surface. This knife's unique blend of functionality, including its ability to scoop up ingredients, makes it an indispensable tool in kitchens, especially where quick and precise preparation of large ingredient volumes is essential.

    C Carbon 1.0%
    Primary hardening element. Raises hardness and wear resistance — but too much increases brittleness and corrosion susceptibility. As a reference: German 1.4112 (~0.5%) sits at the low end; VG-10 (~1.0%) is a common mid-range; SG2 (1.25–1.45%) and ZDP-189 (~3.0%) represent high and extreme ends respectively.
    C
    1.0%
    Cr Chromium 13.5%
    Raises corrosion resistance; 13%+ qualifies steel as stainless. Also improves hardenability and wear resistance. In kitchen use, higher chromium levels contribute to a slight drag or sticking sensation when cutting — a trade-off for the rust resistance it provides.

    The ATS-34 steel, manufacturerd by Hitachi Special Steel, is the Japanese equivalent of the 154CM, famous for its toughness, corrosion-resistance and "high-speed" properties.

    The 154CM was originally designed for jet engine turbine use, however it found its fame in the knife world after legendary knife maker Bob Loveless started using them for his hunters. In the years after that, the 154CM / ATS34 was considered as the top of the line steel by many makers and is still considered so. The high-manganese alloys provides a favorable combination and balance of properties like ductility, formability, strain hardening, and strength.
    Construction: Sanmai - Stainless Clad
    Construction

    Sanmai - Stainless Clad

    Sanmai(Three-Piece) is a common construction for double bevel knives where two pieces of softer cladding steel are forgewelded to each side of a harder core steel. The harder but more brittle core steel will form the hard cutting edge after heat treating, and the softer cladding will support the core to increase the overall strength of the blade.

    The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. And in the case where the cladding steel are stainless in nature, it can offer protection for the carbon or semi-stainless cores against rusting and discoluoring.

    Finish: Tsuchime
    Finish

    Tsuchime

    The "Tsuchime" finish in Japanese kitchen knives refers to a distinctive hammered texture on the blade's surface. This traditional technique not only adds a unique aesthetic appeal but also provides practical benefits, such as reducing drag and preventing food from sticking to the blade during slicing. It's a hallmark of craftsmanship that blends functionality with artistry, making each knife not only a tool but a piece of art.
