The invention concerns a method for clamping a knife of a disc chipper, wherein the knife is pressed from the knife disc via knife a clamp against a wear plate in a diagonal position (α) with respect to the plane of the knife disc with a compressive force (N) substantially parallel with the axis of the knife disc. According to the invention, the compensating force of the force directed to the knife clamp, caused by the diagonal position (α) of the knife and transversal to the compressive force (N) is exerted to the wear plate.
