Abstract

A monofilament line cutting tool is formed by sandwiching a cutting blade between first and second plastic sheets which are thermally bonded to one another. A monofilament line receiving slot in the plastic sheets extends to the blade whereby monofilament line bent into a U-shape may be placed in contact with the blade cutting edge. The plastic sheets are part of spool forming plastic sheet portions which are thermally bonded to one another and shaped into a spool. The plastic sheets forming the tool are selectively pivotable about a live hinge relative to the spool. The plastic sheets can be separated from one another for forming: a sphere generally around the cutting edge; a pair of elongate barrels extending parallel along each side of the monofilament line receiving slot and adjacent the cutting edge; or, a monofilament line receiving cavity extending to the blade cutting edge.
