Abstract

Disclosed is a paper-cutting knife, which comprises a knife body and a knife blade, and is characterized in that a working plane 2 is arranged on the bottom plate of a rigid knife body plate 1; a micro blade 3 is embedded in the working plane 2; the blade sharp of the micro blade 3 is protruding out of the working plane 2; the height of the blade sharp is consistent with the thickness of a would-be-cut paper 5. The micro blade sharp 3 is 45 degrees in angle on both sides. A cutting indication carved groove 4 is arranged on the rigid knife body plate 1; the cutting indication carved groove 4 is superposed with the centerline of the micro blade 3. As the height of the blade sharp is exactly equivalent to the thickness of the paper which is to be cut, the utility model will not lacerate papers below the would-be-cut paper in operation; the knife blade is a hard blade which is 45 degrees in angle on both sides, so that the utility model can repeat movements in both directions when cutting the paper; the utility model which is flexible and convenient to use, will not lacerate papers below the would-be-cut paper or scratch the tabletop, and is suitable for cutting papers of different thickness.
