CobraTec CTK-1 Large OTF Knife 3.25" D2 Tanto Black Aluminum

The CobraTec CTK-1 Large delivers reliable out-the-front deployment with a 3.25-inch D2 steel tanto blade built for demanding cutting tasks. This dual-action automatic knife combines precision engineering with tactical functionality in a compact aluminum frame.

What Makes This Different

The CTK-1 features a dual-action firing mechanism that allows both deployment and retraction at the push of a button, unlike single-action models that require manual blade closure. The D2 tool steel blade maintains a sharp edge longer than standard stainless options while the tanto point geometry excels at piercing and detail work. The integrated glass breaker extends utility beyond cutting applications.

Key Features

• 3.25-inch D2 tool steel tanto blade with superior edge retention
• Dual-action OTF mechanism for one-handed operation
• Black anodized aluminum handle with textured grip surfaces
• Integrated glass breaker for emergency situations
• Removable pocket clip for multiple carry positions
• Safety lock prevents accidental deployment
• Spring-loaded firing mechanism rated for thousands of cycles

Field testing demonstrates consistent blade deployment across temperature ranges from -10°F to 120°F. The aluminum construction reduces weight while maintaining structural integrity under stress. Law enforcement and military personnel rely on OTF knives for situations requiring immediate blade access with gloved hands.
