KATSU FB-X1 Knife, The Brute

KATSU FB-X1 Knife Combines Ancient Inspiration and Modern Force

The KATSU FB-X1 Knife is a brutal, beautiful fusion of centuries-old wisdom and modern-day craftsmanship. Designed by Japanese knife designer Tomoyuki Nemoto, this beast of a blade pays homage to the legendary Chinese cleaver while incorporating the profile and purpose of a Japanese wood-chopping knife. Weighing a staggering 884 grams and stretching over 14 inches in total length, the KATSU FB-X1 Knife isn’t just an addition to your gear collection—it’s the centerpiece.

At first glance, the wide, thick blade commands your attention, but it’s when you wield it that its true purpose becomes clear. This knife is built for hard use. Think chopping wood at a campsite, breaking down big game in the field, or making a statement in your culinary prep area. And yet, despite its mass and might, the FB-X1 remains balanced, thoughtful, and designed for long-term comfort.

KATSU FB-X1 Knife’s massive AUS-10 steel blade is finished with a durable black titanium coating. With a spine thickness of 5mm and a blade width of over four inches, this tool offers tremendous chopping momentum, but it’s the geometry that amplifies its effectiveness. A three-stage folding surface leads to a razor-sharp edge, ensuring that each swing bites deep, clean, and true.

Function isn’t sacrificed for form. The blade features strategically designed lightening grooves and drainage holes that not only reduce weight but enhance blade speed and prevent suction during repeated strikes. These channels, located along the spine side of the blade, serve another crucial role—balancing the weight toward the cutting edge for improved control and less fatigue during prolonged use.

The KATSU FB-X1 Knife is built for real-world durability. The AUS-10 stainless steel is tough, wear-resistant, and well-suited for harsh outdoor conditions. The black titanium finish provides an additional layer of protection, offering rust resistance and low reflectivity for those operating in tactical or survival scenarios.

Equally rugged is the G10 handle, designed for maximum grip and comfort. Textured, water-resistant, and shaped to provide a secure hold under wet or gloved hands, this handle gives you confidence with every swing. The handle is riveted to the full tang of the blade, making it one solid unit capable of absorbing shock while maintaining total control.

To complete the package, the FB-X1 includes a precision-molded Kydex sheath. Lightweight, waterproof, and secure, the sheath makes it easy to carry this beast in the field, whether strapped to a pack, belt or MOLLE rig. MSRP is $399.99.

KATSU FB-X1 Knife: A Legacy in Every Strike

Inspired by the enduring utility of the traditional Chinese cleaver and the raw, unfiltered performance of the Japanese wood-cutting knife, this blade reflects a deep understanding of what an everyday carry tool can be when it’s built without compromise.

With an overall length of 14.29 inches, a blade length of 8.46 inches, and a total weight of 44.98 ounces, the FB-X1 is unapologetically large—but every ounce is put to good use. This is a knife built for action, but it’s also a piece of cultural legacy made tangible in steel, G10, and titanium.
