Rivery Zero File Manual OTF Utility Knife W/ Aluminum Handle - Worn Black Zero-M-OTF-F-6061-Worn Black

The Rivery Zero File Manual OTF Utility Knife with Aluminum Handle in Worn Black is a fresh take on what an everyday utility knife can be when precision machining, thoughtful engineering, and American craftsmanship come together. Designed for professionals who rely on their tools and enthusiasts who appreciate mechanical feel, this manual OTF utility knife delivers a uniquely satisfying experience every time it’s used.

Machined from lightweight 6061 aluminum, the Zero File stands out with its distinctive file-pattern handle. This texture isn’t just for looks—it enhances grip and adds character, while the worn black anodized finish gives the knife a broken-in, work-ready appearance straight out of the box. The satin anodized coating also adds durability, helping the handle resist wear while maintaining a clean, understated look that fits right into any everyday carry setup.

At the heart of the Zero File is its manual out-the-front action. A robust key and spring mechanism drives the blade with a crisp, deliberate slide that delivers a satisfying click and clack during deployment and retraction. It’s smooth, controlled, and intentionally tactile, offering feedback you can feel without relying on springs or assisted action. This responsive mechanism makes even simple cutting tasks feel precise and engaging.

Utility blade compatibility keeps the Zero practical and easy to maintain. When a blade dulls, replacement is quick and straightforward, ensuring the knife stays useful without special tools or proprietary components. This makes it an excellent choice for tradespeople, warehouse work, shop use, or daily tasks where reliability matters more than flash.

A machined lanyard hole adds another layer of versatility, letting you secure the knife to a pack, tool roll, or belt setup for quick access. Compact and portable, it disappears into a pocket yet feels substantial in hand, striking a balance between minimal carry and confident use.

Designed by engineer Michael Sayers and produced by Rivery Manufacturing, the Zero Utility Knife is machined and assembled in East Tennessee. Its seamless, screwless body reflects careful attention to detail and a commitment to clean, functional design. From the first slide to years of hard use, this knife embodies precision, durability, and pride in American-made tools.

A compact utility knife that blends industrial style with addictive mechanical feel, available at SMKW.
