A foldable knife includes a handle, a frame, a cartridge and a blade-driving device. A leaf spring is attached to the frame. The frame is connected to the handle so that it can be pivoted into and from the handle. The cartridge is connected to the frame so that it can be pivoted from the frame for receiving at least one blade and into the frame for feeding the blade. The leaf spring reaches the blade through a slot in the cartridge. The blade-driving device includes a plate, a switch and a connector. The plate is in firm contact with the blade. A primary portion of the switch is located outside the frame and a secondary portion of the switch is inserted into the frame through a slot. The connector connects the plate to the secondary portion of the switch so that the blade is movable via operating the switch.
