The Tekto A3 Delta is a full‑size automatic folding knife engineered for durability, control, and rapid deployment in demanding conditions. The drop‑point blade measures 3.60 inches and is manufactured from D2 tool steel with a titanium coating, hardened to a range of 60–62 for enhanced edge retention, wear resistance, and long‑term toughness. Blade deployment is driven by a push‑button automatic mechanism that delivers swift, consistent opening, reinforced by an integrated safety switch that helps prevent unintentional activation and secures the blade during carry. Overall open length measures 8.90 inches, offering substantial cutting reach and leverage for hard‑use applications.

The handle is constructed from G10 and shaped with ergonomic contours and strategic jimping to promote a secure, confident grip under stress. Handle length measures 5.20 inches with a slim 0.54‑inch width, balancing full‑size control with practical carry, while total weight remains approximately 5.96 ounces. Integrated features include a glass breaker for emergency use, a lanyard hole for retention options, and an ambidextrous pocket clip to support versatile carry preferences. Designed as a robust automatic platform, the A3 Delta emphasizes strength, reliability, and safety for users who demand uncompromising performance from a tactical‑ready folding knife.
