Abstract

The invention discloses a folding knife having a knife handle and a blade. A pivotal shaft is at an end of the knife handle; a limit slot is inside the knife handle; and a latch element is in the limit slot. The blade is pivotally coupled to the knife handle through the pivotal shaft. The blade includes a protruding pillar corresponding to a latch portion. When the blade is stored into the knife handle, the protruding pillar is fixed between the limit slot and the latch element, and the blade will not pivot out of the knife handle due to shakes or vibrations. If a predetermined force is applied to rotate the blade towards the knife handle, the protruding pillar will rotate in conformity with the blade and push the latch element, so that the protruding pillar is released and rotated with the blade in the limit slot.
