CRKT LCK + Large Folding Knife Assisted Opening 3 3/5" Blade Black

The CRKT LCK + Large Folding Knife with Assisted Opening and 3 3/5" Black Blade is engineered for operators who demand instant blade deployment without compromise on size or weight. This everyday carry folding knife combines Columbia River Knife & Tool's assisted opening innovation with IKBS ball bearing pivot technology to deliver one of the fastest, smoothest blade presentations available in the mid-size folding knife category.

The LCK + Large deploys via flipper mechanism with assisted spring assistance, significantly reducing the time between decision and readiness—critical in tactical scenarios where hesitation costs seconds. At just 0.17 lbs, the knife remains lightweight enough for extended carry without gear fatigue, while the 3 3/5" blade provides sufficient edge length for utility cuts, food prep, and tactical tasks. The IKBS ball bearing pivot ensures the blade tracks smoothly through the full arc of deployment and operates with minimal play after extended use, maintaining reliability across thousands of cycles.

This knife is designed for law enforcement, military personnel, first responders, and serious outdoor professionals who rely on a folder for daily carry. The assisted opening mechanism makes it accessible to users who may have limited hand strength while maintaining the legal compliance profile of a folding knife in most jurisdictions. Construction emphasizes durability without excess weight, making the LCK + Large suitable for patrol duty, training operations, emergency response, and backcountry work where tool reliability matters.

The assisted opening category has become the standard for professional-grade folding knives because it eliminates the physical coordination demand of manual deployment while preserving the compact profile of a folder. The LCK + Large competes directly with purpose-built tactical folders from established manufacturers and represents CRKT's commitment to balancing speed, portability, and real-world utility.
