Shirogorov Knives – SHI-Q-AW-B – Ursus Quantum – Folding Knife – Cromax PM Stonewash Upswept – Titanium Ash Wood Inlay – Grey Brown

The Shirogorov Knives SHI-Q-AW-B (Ursus Quantum) is a high-end folding knife engineered for both collectors and serious users. With refined ergonomics, premium materials, and precision machining, it exemplifies the strength, balance, and craftsmanship Shirogorov is known for. This version features a 3.74-inch stonewashed Cromax PM blade, optimized for durability and edge retention. The spine is lightly jimped for improved grip and tactile control under thumb pressure. The blade thickness is a solid 3.4036 mm (0.134 in), giving it a rugged presence without excessive bulk. In the open configuration, the knife spans 8.86 inches overall, with a balance that places control confidently in the hand. It weighs approximately 4.4 ounces (≈ 124.7 g), delivering a feel that is firm yet not overly heavy for most users. The pivot system operates on a Multi-Row Bearing System (MRBS), enabling buttery smooth deployment and retraction. All external hardware—including pivot screws, frame screws, and standoffs—is stonewashed to create a cohesive, low-glare aesthetic that resists fingerprints. One of the standout features is the titanium frame lock handle, which is reinforced with a steel lock bar insert to enhance durability and lockup security. The handle scales are made of titanium with Brown Ash wood inlays, lending a touch of natural warmth to the design. Internally, the liners are lightly milled to reduce weight without sacrificing structural integrity. The backspacer is delivered in satin-finish titanium, complementing the overall metallic palette. For carry, it uses a tip-up, 3D-machined stonewashed titanium pocket clip, which hides its mounting screw for a clean look.
