The Tekto A3 Delta is a full‑size automatic folding knife engineered for durability, control, and rapid deployment in demanding conditions. The serrated 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 cutting performance. The serrations increase effectiveness on fibrous materials such as rope, webbing, and strapping. Blade deployment is driven by a push‑button automatic mechanism that delivers fast, consistent opening and is reinforced by an integrated safety switch designed to help prevent unintentional activation. Overall open length measures 8.90 inches, providing substantial reach and leverage for hard‑use cutting tasks.

The handle is constructed from forged carbon, offering a rigid yet lightweight structure with a distinctive surface pattern and excellent strength. Ergonomic contouring and strategic jimping promote a secure, confident grip during high‑stress use. Handle length measures 5.20 inches with a slim 0.54‑inch width, balancing full‑size control with effective carry characteristics at an overall weight of approximately 5.96 ounces. Integrated features include a glass breaker for emergency situations, a lanyard hole for retention or customization, and an ambidextrous pocket clip to support flexible carry options. The A3 Delta emphasizes strength, reliability, and safety in a tactical‑ready automatic platform.
