RIVERY ZERO CAB LAB COLLABORATION SMOOTH OPERATOR OTF UTILITY GREEN ALUMINUM HANDLE ZERO-M-OTF-S-6061-CADLAB GR

The RIVERY Zero Cab Lab Collaboration Smooth Operator OTF Utility Knife is where refined aesthetics meet precision engineering. Built on the trusted Zero platform, this special-edition model pairs the rugged reliability of American machining with a sleek, green anodized finish that sets it apart from anything else in your kit. The “Smooth Operator” handle treatment on 6061 aluminum provides a clean, polished feel in hand—no harsh textures, just a seamless surface that’s as comfortable as it is striking.

This knife isn’t just about looks. At its core is a replaceable stainless steel razor blade, delivering sharp, dependable cutting performance. The manual thumb-slide OTF (out-the-front) deployment and retraction system is crisp and deliberate, powered by a robust spring and precision-machined carriage. Every click and clack is satisfyingly solid, making this tool as addictive to operate as it is practical to use.

The Zero’s carriage is designed for broad blade compatibility, fitting most two-notch utility blades on the market. Known compatible options include Workpro SK5 (61mm), Dewalt Carbide Edge, Rapid Edge Serrated, Milwaukee, Titan, Berkling SK2h black, Jet SK5 Titanium coated, and many unbranded SK5 blades. For best results, avoid Fiskars and ceramic blades.

This collaboration with Cab Lab takes the Zero’s already exceptional build and elevates it with premium post-machining processes and a custom anodized finish that standard production simply can’t replicate. Machined in East Tennessee and metal-finished in West Palm Beach, Florida, every step reflects the dedication of skilled American machinists and anodizing specialists.

Sized for everyday carry without compromise, the Smooth Operator measures roughly 2.7 inches closed and 3.2 inches overall. It’s lightweight yet rugged, equally at home in a professional setting or in the pocket of someone who demands quality tools. The handle features a precisely machined lanyard hole for carry customization (lanyard not included).

Whether you’re breaking down boxes, trimming materials, or simply enjoying the tactile precision of its OTF action, the RIVERY Zero Smooth Operator stands as a fusion of function, form, and American craftsmanship. Check out this utility knife with a smooth style handle by Rivery at SMKW!
