Abstract: A folding camp knife (10) comprises an elongated handle case (12) having sideplates (24a and b) separated by a blade gap (26) in which a blade (14) is mounted for rotation by means of an axle pin (16) passing through holes (30 and 54) in the sideplates and the blade. A locking piece (18) engages the axle pin on the outside of the handle case and can both rotate about and slide longitudinally along the axle pin. The locking piece includes a locking flag (68) which can be moved into handle and blade peripheral locking slots (38a and b and 52) when they are in registration. Once the locking flag is slid into these peripheral locking slots the axle pin can be tightened against the locking piece to prevent further movement of the locking piece, thereby preventing rotational movement between the blade and the handle case. The axle end of the blade has a plurality of locking slots (52a-e) extending thereabout which allow the blade to be placed at various angles.
