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.

Claims

1. A monofilament line cutting tool comprising:

a cutting blade having a cutting edge;

a first plastic sheet;

a second plastic sheet bonded to said first plastic sheet;

wherein said cutting blade is sandwiched and retained between said first and second plastic sheets;

wherein said first and second plastic sheets are separated from each other in an area adjacent said blade for thereby forming a monofilament line receiving cavity extending to said blade cutting edge, whereby a monofilament line can be cut by bending into a U-shape and inserting the U-shape into said cavity and contacting said cutting edge;

a flap secured to said first plastic sheet or said second plastic sheet, said flap extending into said cavity and being moveable by inserting the monofilament line U-shape into the cavity and slidingly pushing the U-shape against the flap; and

,

further wherein said first and second plastic sheets are each part of respective first and second spool forming plastic sheet portions, wherein said first and second spool forming plastic sheet portions are shaped and adhered to each other forming a spool for wrapping the monofilament line thereon.

2. The monofilament line cutting tool of claim 1 comprising a live hinge between said first and second plastic sheets and said first and second spool forming plastic sheet portions, whereby said first and second plastic sheets are selectively pivotable about said hinge relative to said spool.

3. A monofilament line cutting tool comprising:

a cutting blade having a cutting edge;

a first plastic sheet;

a second plastic sheet bonded to said first plastic sheet;

wherein said cutting blade is sandwiched and retained between said first and second plastic sheets;

wherein said first and second plastic sheets are separated from each other in an area adjacent said blade for thereby forming a monofilament line receiving cavity extending to said blade cutting edge, whereby a monofilament line can be cut by bending into a U-shape and inserting the U-shape into said cavity and contacting said cutting edge;

a flap secured to said first plastic sheet or said second plastic sheet, said flap extending into said cavity and being moveable by inserting the monofilament line U-shape into the cavity and slidingly pushing the U-shape against the flap; and

,

wherein said cutting blade is planar shaped and is located perpendicular to said first and second plastic sheets.

4. The monofilament line cutting tool of claim 3 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

5. The monofilament line cutting tool of claim 3 wherein said flap includes a blade receiving slot, said blade extending through said flap blade receiving slot.

6. A monofilament line cutting tool comprising:

a cutting blade having a cutting edge;

a first plastic sheet;

a second plastic sheet bonded to said first plastic sheet;

wherein said cutting blade is sandwiched and retained between said first and second plastic sheets;

wherein said first and second plastic sheets are separated from each other in an area adjacent said blade for thereby forming a monofilament line receiving cavity extending to said blade cutting edge, whereby a monofilament line can be cut by bending into a U-shape and inserting the U-shape into said cavity and contacting said cutting edge;

a flap secured to said first plastic sheet or said second plastic sheet, said flap extending into said cavity and being moveable by inserting the monofilament line U-shape into the cavity and slidingly pushing the U-shape against the flap; and

,

wherein said flap includes a bent terminal end bearing against said first plastic sheet or said second plastic sheet and forming a spring whereby said flap is maintained in a normally closed position.

7. A monofilament line cutting tool comprising:

a cutting blade having a cutting edge;

a first plastic sheet;

a second plastic sheet bonded to said first plastic sheet;

wherein said cutting blade is sandwiched and retained between said first and second plastic sheets;

wherein said first and second plastic sheets are separated from each other in an area adjacent said blade for thereby forming a monofilament line receiving cavity extending to said blade cutting edge, whereby a monofilament line can be cut by bending into a U-shape and inserting the U-shape into said cavity and contacting said cutting edge;

a flap integrally formed with and hingedly secured to said first plastic sheet or said second plastic sheet along a hinge axis, said flap extending into said cavity;

wherein said cutting blade is planar shaped and is located generally perpendicular to said flap hinge axis; and

,

wherein said flap is normally in a closed position obstructing access of said cutting edge from a cavity opening and, for accessing the cutting edge, said flap is moveable about said hinge axis toward an open position by inserting the monofilament line U-shape into said cavity and slidingly pushing the U-shape against the flap.

8. The monofilament line cutting tool of claim 7 wherein said cutting blade is planar shaped and said flap includes a blade receiving slot, said blade extending through said flap blade receiving slot.

9. The monofilament line cutting tool of claim 7 wherein said flap includes a bent terminal end bearing against said first plastic sheet or said second plastic sheet and forming a spring whereby said flap is maintained in its said normally closed position.

10. The monofilament line cutting tool of claim 7 further wherein said first and second plastic sheets are each part of respective first and second spool forming plastic sheet portions, wherein said first and second spool forming plastic sheet portions are shaped and adhered to each other forming a spool for wrapping the monofilament line thereon.

11. The monofilament line cutting tool of claim 10 comprising a live hinge between said first and second plastic sheets and said first and second spool forming plastic sheet portions, whereby said first and second plastic sheets are selectively pivotable about said hinge relative to said spool.

12. The monofilament line cutting tool of claim 7 wherein said cutting blade is planar shaped and said cutting blade is perpendicular to said first and second plastic sheets.

13. A monofilament line cutting tool comprising:
