Tsuchime Kurouchi Super Aogami Petty 135mm

TSUCHIME KUROUCHI SUPER AOGAMI SERIES

Fukui Co., Ltd. created this knife series with pure practicality in mind—designed to thrive in the harshest environments of professional kitchens rather than sit behind glass in a display cabinet.
 

The "Rugged" Finish Philosophy (Tsuchime Kurouchi)
 

- Kurouchi Blacksmith Finish: The oxide layer formed during the forging process is intentionally preserved, acting as a natural shield that helps protect the carbon steel cladding from rust and discoloration when exposed to acidic ingredients.

- Deep Tsuchime Hammered Texture: The pronounced hammered indentations reduce the blade's direct contact area, minimizing vacuum suction during cutting. As a result, moisture-rich or sticky ingredients such as potatoes, radishes, and onions naturally fall away from the blade instead of clinging to its sides.
 

2. Mechanical Strength from the Ultimate Core Steel (Aogami Super)
 

- The Pinnacle of Carbon Steels: The Aogami Super core (63–64 HRC) is enhanced with tungsten for superior edge retention and vanadium for improved wear resistance. This creates an exceptionally fine grain structure that allows the blade to bite decisively into ingredients without slipping.
 

- The "Micro-Serrated" Cutting Effect: One of the defining characteristics of this steel is its remarkable ability to maintain cutting aggression over extended periods. Even after a long shift, when the edge begins to lose its peak sharpness, the steel structure continues to preserve microscopic serrations that allow the knife to slice smoothly instead of feeling abruptly dull.

3. The Support of the Oak Handle and Sakai Sharpening Craftsmanship
 

- Forward-Balanced Weight Distribution: The octagonal oak handle features a dense grain structure and carries more weight than traditional Ho wood. Combined with the substantial Sakai-style blade profile, it shifts the balance point slightly toward the front of the knife. This natural weight allows the user to simply guide the blade while the knife itself completes the cut with minimal wrist effort.
 

- Refined Spine and Choil Treatment (Agito & Spine): Fukui Co., Ltd. requires its sharpeners to ease the edges of the spine and round off the sharp corners around the choil (Agito). As a result, even after hours of continuous pinch-grip use, the areas of the hand in contact with the metal remain comfortable, eliminating irritation, discomfort, and callus formation.
 

A knife defined by rugged practicality, showcasing the striking contrast between its raw black-forged blade and bright oak handle. It sacrifices polished elegance in favor of an exceptionally durable cutting edge, highly effective mechanical food release, and an ergonomic feel built specifically for demanding work.
