Opening the knife is effortless and smooth thanks to the ball bearing ORB Pivot System. The handle is made of titanium and has a frame lock design, providing a comfortable grip with its refined angles and edges. Additionally, the QTR-5ZLT comes with a pocket clip that can be adjusted for left or right-handed users, allowing for convenient tip-up carry.
