Fujiwara Yasuhiko Aogami Super / Blue Super Steel Santoku 165 mm / 6.5" Red Handle

Eliminate Kitchen Prep Friction: Laser Slicing Without the Wedging

Tired of knives that wedge and split dense daikon, crush delicate heirloom tomatoes, or drag through boneless proteins? The Fujiwara Yasuhiko Aogami Super Santoku 165 mm is engineered to eliminate kitchen prep resistance entirely.

Forged to an ultra-slender 1 mm spine and weighing a featherlight 137 grams, this knife falls into the coveted "laser" category of Japanese cutlery. It drops through dense root vegetables, shallots, and meats on pure geometry alone, delivering effortless cutting precision that dramatically reduces hand fatigue during long prep sessions.

Aogami Super Core: 64–65 HRC Slicing Bite

At the heart of the blade is Hitachi Aogami Super (Blue Super Steel), quenched and tempered to 64–65 HRC. Fortified with tungsten, molybdenum, and high carbon content, Aogami Super takes a hair-splitting apex that holds its aggressive cutting bite far longer than standard German or conventional Japanese stainless alloys.

Stainless Cladding (San Mai): Demystifying Carbon Steel Care

Many cooks hesitate to buy high-carbon steel because they worry about rust. This knife eliminates 95% of that concern through San Mai laminate construction:

• Protective Stainless Cladding: The entire exterior blade face is clad in rust-proof stainless steel. Only the exposed 2–3 mm cutting core at the sharpened edge is reactive carbon steel.
• The Beauty of Patina: Over time, the exposed Aogami Super cutting core will naturally oxidize into a rich, protective blue-gray patina. This patina is completely food-safe and actively acts as a natural barrier against red rust.
• Simple 2-Step Care:
1. Wipe the blade dry with a clean kitchen towel between prep tasks (especially after cutting acidic citrus or onions).
2. Hand-wash with warm water and mild soap immediately after use, dry thoroughly, and store dry. Never use a dishwasher.

Functional Tsuchime (Hammered) Finish

The upper blade face features a hand-hammered Tsuchime pattern. These hand-forged indentations create natural micro-air pockets between the blade and your food, disrupting surface suction so starchy potatoes, cucumber slices, and proteins release cleanly with every downward cut.

The Artisan: Dentō Kōgeishi Yasuhiko Fujiwara

This knife is not a mass-manufactured factory blade; it is hand-forged by Yasuhiko Fujiwara, an officially certified Dentō Kōgeishi (Master of Traditional Crafts) by Japan's Ministry of Economy, Trade and Industry (METI).

Working out of Miki City, Hyogo Prefecture—Japan’s historic hardware capital with over 400 years of blacksmithing heritage—Fujiwara is the third-generation successor of Fujiwara Kogatana Seisakusho, founded in 1927. Drawing on his family’s founding lineage in forging traditional kogatana (small utility blades requiring microscopic edge precision), Master Fujiwara personally shapes, hammer-forges, and hand-tempers each blade using coal fires and water-quenching guided by decades of sensory mastery.

Red Wood Ergonomic Western-Style Handle

Fitted to the blade is a contoured Western-style ergonomic handle crafted from dense, polished red wood. Designed for chefs who prefer the familiar palm-filling comfort and balance of a Western grip over a traditional Wa-handle, this handle features sculpted finger contours that lock naturally into the hand. It provides exceptional grip security, lateral stability during push-cuts, and fatigue-free comfort during heavy prep work.

Authorized Dealer Direct

Hasu-Seizo is an authorized partner sourcing directly from Fujiwara Kogatana Seisakusho in Miki City, Japan. Before leaving our Seattle area warehouse, every blade undergoes physical quality control to confirm absolute straightness along the 1 mm spine, symmetrical bevel geometry, and a flush handle seal.

Sharpening & Care Guidelines

• Whetstone Maintenance: Hardened to 64–65 HRC, Aogami Super responds with unmatched feedback on Japanese whetstones. Maintain the apex using a medium whetstone (#1000 grit) and polish on a fine whetstone (#5000 to #8000 grit) followed by leather stropping.
• Cutting Technique: This is a precision laser blade built for fluid push-cuts, pull-cuts, and light rocking. Avoid twisting or lateral torque.
• Prohibited Uses: Do not cut bones, frozen foods, hard nutshells, or dense cheese rinds. Hacking hard targets will cause the thin edge to chip.

Frequently Asked Questions

Will the Fujiwara Yasuhiko Aogami Super Santoku rust easily?

No. Because the blade features San Mai stainless steel cladding, 95% of the blade is rust-proof. Only the exposed 2–3 mm cutting core at the edge is reactive and requires wiping dry after use.

What is the advantage of an ergonomic Western handle on a Japanese blade?

An ergonomic Western handle provides a contoured, palm-filling grip that offers greater lateral stability and familiar hand ergonomics for Western cooks, paired with the superior sharpness of Japanese laser steel.

What does the Dentō Kōgeishi certification signify?

Dentō Kōgeishi is a prestigious certification granted by the Japanese government (METI) recognizing master craftsmen with decades of proven expertise in preserving traditional, hand-forged Japanese manufacturing techniques.

What is the benefit of the hammered Tsuchime finish?

The hammered indentations create natural air pockets across the blade face. This breaks the vacuum seal that typically causes wet vegetables like potatoes and cucumbers to stick, allowing slices to drop cleanly onto the cutting board.

Is a wooden saya sheath included with this knife?

No, a wooden saya is not included. The knife ships in an authentic Japanese presentation box with a protective plastic edge sleeve for safe transit.

Where does this knife ship from?

All inventory is inspected, packaged, and shipped directly from our warehouse located in the Seattle area.
