ABSTRACT:
A folding knife having a blade and a pair of folding handles. The handles are channel shaped and bifurcated at one end for receiving one end of the blade. The bifurcated ends of the handles are attached to the blades by adjacent pivot pins. Rotation of the handles to the closed position encloses the blade inside the opposing channels of the handles. The ends of the handles are coupled by meshing gears pivoted on the same pins so that the handles must rotate together in opposite directions through 180.degree. between closed and open positions.
