Abstract

A process of cutting monofilament line using a cutting tool including a tool body having a cavity for insertion of a bent portion of the monofilament line. A cutting blade is provided in the cavity and a pair of opposing walls in the cavity are located generally parallel to and on either side of the cutting blade. For cutting, the monofilament line is bent into a U-shape portion which is inserted into the cavity with the legs of the U-shape portion adjacent the respective opposing walls, thereby placing the outer exterior surface of the monofilament line at the bottom of the U-shape portion in tension and the inner exterior surface of the bottom of the U-shape portion in compression. As the U-shaped portion is inserted into the cavity, the outer exterior surface at the bottom of the U-shape portion is placed against the cutting blade thereby cutting the monofilament line.

Claims

1. A process of cutting monofilament line with a cutting tool including a tool body, a cutting blade, and a wall adjacent to the cutting blade, said process of cutting comprising the steps of:

bending the monofilament line into a U-shape portion and inserting the U-shape portion into the tool body placing at least one of legs of the U-shape portion against the wall and placing an outer exterior surface at a bottom of the U-shape portion in tension and an inner exterior surface of the bottom of the U-shape portion in compression; and

,

placing the outer exterior surface at the bottom of the U-shape portion against the cutting blade thereby cutting the monofilament line.

2. The process of claim 1 wherein the cutting tool further includes retaining walls located perpendicular to the cutting blade and wherein, during said step of inserting, the legs of the U-shape portion are retained against the wall.

3. The process of claim 1 wherein, the cutting tool further includes retaining walls located perpendicular to the cutting blade and wherein, during said step of inserting, the legs and bottom of the U-shape portion are retained in a plane generally perpendicular to the cutting blade.

4. The process of claim 1 wherein the tool body is located on a spool of monofilament trimmer line and wherein the monofilament line is cut to a length sufficient for use in a trimmer.

5. The process of claim 1 wherein the legs of the U-shape are retained generally equidistant from the cutting edge.

6. The process of claim 1 wherein, after the monofilament line is cut, the cut ends of the legs of the U-shape extend beyond the cutting edge.

7. The process of claim 1 wherein the legs of the U-shape portion are retained generally equidistant from the cutting edge and wherein, after the monofilament line is cut, the cut ends of the legs of the U-shape extend beyond the cutting edge.
