  • Patent number: 10279489
    Abstract: The present invention provides a cutter knife, which even if made with only the metal parts, smoothness of sliding operation of the blade is not degraded in time, even without lubricating oil nor friction resistant coating, A slider of the cutter knife carries rolling member, which is made rolling contact with the outer surface of the cutter knife. Further, the slider has a protrusion which extends into the cutter knife body and is engaged into a hole formed on the blade. Since an external force applied onto the slider is received by the rolling member, the slider can be operated smoothly. Besides, the height of the protrusion is determined, such that the protrusion does not touch the inner surface of the cutter knife. Thus, the protrusion tip never interfere with the inner surface of the cutter knife, thereby the sliding operation of the slider would not be prevented.
