The CobraTec Karambit automatic OTF knife (brand part no. CTBK-RH) is a fully automatic double-action out-the-front folder built by CobraTec Knives around a curved 2.75-inch karambit blade in stonewashed D2 steel. A thumb-activated switch mounted near the retention ring deploys the blade automatically, with no manual force required beyond pressing the switch, making it a genuine automatic knife rather than an assisted-opening manual folder. The black anodized 6061-T6 aluminum handle includes a finger ring for reverse-grip retention and control, along with a pocket clip for right-hand carry. Built for the karambit enthusiast or self-defense-minded carrier who wants true automatic deployment in a curved-blade format.

Key Specifications

• The blade measures 2.75 inches long, curved in classic karambit style.
• The blade is made from D2 steel with a stonewashed finish for corrosion resistance.
• The blade uses a plain edge ground for the karambit’s characteristic slashing and hooking cuts.
• The handle is built from black anodized 6061-T6 aluminum for a light, durable grip.
• A finger ring on the handle secures the knife in reverse-grip carry and improves retention.
• Overall open length is 8.375 inches, with a closed length of about 5.875 inches.
• The knife weighs about 4 ounces, light enough for daily carry.
• Deployment is automatic out-the-front, fired by a thumb-activated switch by the retention ring.
