Vosteed Porcupine TiSlim Folder S90V ACD WSH-STN WSH Blade Acid Wash Gray TI Handle

The Vosteed Porcupine TiSlim Folding Knife (Model A4805) delivers a sleek, lightweight EDC platform built for precision, control, and modern materials. Designed by Yue Dong, it combines slim titanium construction with a high-performance blade profile, creating a knife that feels refined in hand while still being fully capable in daily cutting tasks. At 7.22 inches overall, it carries easily in the pocket without sacrificing usable blade length or strength.

The blade is crafted from premium S90V steel, heat-treated to HRC 60±1, offering exceptional edge retention and strong corrosion resistance for long-term use. Finished in a layered acid wash and stonewash, it presents a rugged, low-glare appearance that also helps conceal wear from daily carry. The flat grind enhances slicing efficiency, giving the blade a smooth, controlled cutting feel that performs well across a wide range of materials. At 3.04 inches long and just 2.20 mm thick, the blade is thin, responsive, and optimized for clean, precise cuts rather than bulk-heavy chopping.

Deployment is handled through stainless steel thumb studs, providing quick, reliable one-handed access with a familiar and controlled motion. Inside, a caged ceramic ball bearing pivot assembly ensures smooth, consistent action that feels effortless from open to close. The top liner lock secures the blade with confidence, delivering solid lockup while still allowing controlled disengagement when the task is complete.

The handle is machined from gray titanium, giving the Porcupine TiSlim a lightweight yet durable foundation with a clean, modern profile. Subtle blue accent details add a pop of color that breaks up the industrial tone, giving the knife a distinctive visual identity without overwhelming its minimalist design. At just 2.97 ounces, it carries exceptionally light in the pocket, making it ideal for everyday carry where comfort matters as much as capability. The 0.315-inch thickness and ergonomic shaping provide a secure, natural grip during use.

A non-reversible titanium pocket clip set for tip-up carry ensures stable, low-profile transport. Every key structural element is built with precision in mind, reinforcing durability while keeping the design streamlined and functional.

The Porcupine TiSlim reflects Vosteed’s commitment to modern EDC engineering, pairing high-end S90V performance with titanium construction and a slim, pocket-friendly design that doesn’t compromise on usability.
