Frame Lock Knives

In a frame lock knife, the knife handle—its “frame”—consists of two plates of material on either side of the blade. To ensure a secure lock up, one or both of these plates is usually metal. When the knife is opened, the metal side of the frame, the lockbar, butts up against the backend of the blade (the tang) and prevents the blade from closing. To close a frame lock knife, the user pushes the frame to the side, unblocking the blade, and folds the blade back into the handle. Like locking liner knives, frame locks are manufactured so that the locking side of the frame is angled toward the interior of the knife, creating a bias toward the locked position. Both the blade tang and the lockbar are precisely angled so they fit together for a secure, reliable lockup. The thickness of the frame material blocking the blade open makes the frame lock extremely sturdy.
