Specifications

Design & Materials

The CUBIS BG42B is a Bestech in-house design, reflecting the brand's own approach to a full-size, versatile everyday carry folder. At 3.15" the blade is long enough for demanding cutting tasks while the 4.33" closed length keeps the knife pocketable and unremarkable in daily carry. The stonewash plus satin dual finish combines a stonewash texture on the blade flats — which conceals wear, corrosion, and micro-scratches — with a satin-polished edge bevel that clearly shows the blade geometry and makes sharpening easy to evaluate.

D2 tool steel is a high-carbon, high-chromium semi-stainless tool steel renowned for outstanding edge retention and wear resistance, making it a preferred choice for knives intended for working use. Users who demand a long-lasting cutting edge and are willing to maintain their blade will find D2 an excellent value proposition at the CUBIS BG42B's price point.

The beige Micarta handle sets the CUBIS BG42B apart from the darker, more tactical colorways common to D2-bladed folders. Micarta is a composite of natural fiber layers — typically linen or canvas — infused with resin under high pressure. The result is a handle material that is warm and organic to the touch, moisture-resistant, and develops a subtle patina with regular carry and use that makes each knife genuinely individual over time. Beige Micarta in particular pairs naturally with the dual-finished D2 blade for a cohesive, earthy aesthetic suited to both outdoor and everyday urban carry.

Liner Lock Mechanism

The CUBIS BG42B's Liner Lock uses a sprung steel liner inside the handle that snaps behind the blade tang when the knife is fully deployed, providing positive, rattle-free lockup. This proven mechanism requires no adjustment over time and engages automatically with every opening. To close, press the liner aside with your thumb and fold the blade back into the handle safely.
