The Sig Sauer Counterstrike is a lightweight, fast‑deploying double‑action OTF built around a 3.35‑inch CPM 20CV tanto blade that’s 0.125 inches thick, hardened to 59–61 HRC, cryogenically treated, finished in Black PVD, and hand‑sharpened for a precise cutting edge.

Measuring 5 inches closed and 8.35 inches overall at just 2.9 ounces, it features ambidextrous trigger deployment and retraction, paired with a matte black 6061‑T6 hard‑anodized aluminum frame and a Black Polyamide Nylon 12 cover that matches Sig’s Nitron firearm finish. Additional features include a deep‑carry tip‑down pocket clip for right‑ or left‑handed carry, plus a removable carbide glass breaker with a lanyard loop and replacement filler screw.
