A Blade Born From Duty
Mononofu is not a production knife. It was never designed to be sold in a store. It was designed to stop a threat, survive a mission, and outlast the person carrying it. Everything else came after.
The Fifty Six — Original duty model. Full-tang construction.
It Started With a Request That Could Not Be Traced
A member of a US police special unit needed knives for duty work. Not a catalog knife. Not something off a shelf. Something that could handle the kind of stress that most blades are never tested against. Through channels that required anonymity, that request reached Shoji Kazunori, representative of USPD GEAR.
Shoji found master craftsman Igarashi. Working from rough sketches, the two went through round after round of prototypes — refining geometry, balance, thickness, and edge profile until the blade was exactly what a professional would trust with their life. That knife became the Fifty Six.
Mononofu (武士 / もののふ) — an ancient Japanese word for warrior. Not a marketing name. A declaration of what the blade is for.
Shoji Kazunori — The Man Behind the Brand
Shoji Kazunori is the representative of USPD GEAR and the driving force behind MONONOFU. His background is not in product design or marketing. It is in Battodo — the Japanese art of sword drawing and cutting — in which he holds a 5th Dan rank and has won national competitions at every level.
He is also a World Speed Shooting Championship Grand Master. When Shoji designs a knife, he is not thinking about display cases. He understands exactly what a blade must do under stress, and builds to that standard.
His collaboration with master craftsman Igarashi produced both the Fifty Six series and the Yoroidoshi — a short, armor-piercing blade modeled after the legendary tanto carried by samurai to penetrate plate armor.
"Every knife we make goes through the same process as a real battle test. We do not release a blade until we are certain it will not fail the person carrying it."
— Shoji Kazunori, USPD Gear
No Machines. No Assembly Lines. No Shortcuts.
Every Mononofu knife is built entirely by hand by master craftsman Igarashi in Japan. Steel is selected, shaped, heat-treated, ground, polished, and fitted without automation at any stage.
VG10 & Forged Carbon
Two steel options. VG10 stainless — sand polished, corrosion resistant, proven in field use. Forged carbon steel — harder, sharper, developed through traditional Japanese smith techniques. Both are selected for performance, not aesthetics.
Full-Tang. Always.
Full-tang construction was a requirement from the professionals who commissioned the original design. The steel runs the full length of the handle. Nothing fails at the joint because there is no joint.
Made to Order, Made Once
Each knife is made after an order is placed. Craftsman Igarashi works on one blade at a time. Lead time is 6 to 8 weeks. You are not buying a product from inventory. You are commissioning a knife.
The Yoroidoshi
Yoroidoshi means armor piercer. The original was a short, thick tanto carried by samurai specifically to penetrate plate armor. Where a standard blade would deflect, the Yoroidoshi would not.
The Mononofu Yoroidoshi was praised immediately by the professionals who reviewed it. Short, sturdy, and designed for close-in work. Every angle serves a purpose worked out through years of iteration and field feedback.
View the YoroidoshiThe American Impact Test
Claiming a knife is strong is not a test. Mononofu runs what Shoji calls the American-style impact test — live fire, point-blank, against each blade profile.
The protocol is straightforward: thinner blades are tested with handgun rounds, progressively thicker profiles with higher-powered cartridges. A blade either passes or it does not ship.
The Yoroidoshi passed its bulletproof test. The footage is public. This is not a stunt — it is standard procedure for every Mononofu model before release.

When a blade survives a direct rifle impact, you know two things: the steel is correct, and the heat treatment is correct. These are the two things that cannot be faked in a handmade knife. No certification process tells you more than a round downrange.
Featured in Arms Magazine Japan
Mononofu has been profiled in Arms Magazine, Japan's leading publication for tactical gear and weapons. Coverage is earned through performance, not press releases.
Japan's foremost tactical gear publication ran a feature interview with Shoji Kazunori, covering the origin of MONONOFU, the collaboration with craftsman Igarashi, and the engineering behind the impact testing protocol.
Lumina 28 Design is the authorized US distributor for MONONOFU knives. We work directly with Shoji and USPD GEAR. Every knife ships from Japan with full documentation of its origin and construction.
Every Knife Is Made for One Person
You choose the steel, the blade style, and the handle. Craftsman Igarashi builds it. Your knife takes 6 to 8 weeks. It will be the last knife you order.
