Crossbar Open

The crossbar lock is one of the most secure and ambidextrous locking mechanisms in modern folding knives. By pulling the bar back, the blade is free to swing open or closed with ease. This style is popular for its smooth action, rock-solid lockup, and left/right-hand usability.

Thumb Slide (OTF)

Common on OTF (out-the-front) knives, the thumb slide uses a switch or slider to deploy the blade straight out of the handle. It’s aggressive, fast, and highly satisfying to operate.
