The current invention addresses these issues in a simple yet effective way. The engagement between the blade and handle is extremely strong when locked, yet can be easily moved with the tip of a finger when the actuating means is engaged. Thus the blade is held rigidly in both the open and closed positions by the interlock and is easily changed in an ergonomically intuitive flick of one finger. The preferred method is to use a cam or cams to rotate against the frame, pivoting near the center of the blade, perpendicular to the axis of blade rotation. Thus the entire knife is composed of three primary parts: the blade, the frame and the cam. No additional springs are needed to effect the mechanism. Another desired feature is an integrated lanyard clip which is designed into the interface of the cam and blade surfaces. This clip is located in a way that allows the user to "pluck" the knife from a ring or lanyard. A belt clip can also be affixed to the u shaped member. This would allow an alternative means of securing the knife for ease of storage.
