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 sheet;

a monofilament line receiving slot in said first and second plastic sheets extending to said cutting edge, whereby a monofilament line can be cut by bending into a U-shape and inserting the U-shape into the slot and contacting said cutting edge; and

,

wherein said first and second plastic sheets include half sphere shaped projections adjacent said cutting edge which together form a sphere generally around said cutting edge with a portion of the cutting edge accessible for cutting the monofilament line, while the projections obstruct other access to the cutting edge.

2. The monofilament line cutting tool of claim 1 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

3. The monofilament line cutting tool of claim 1 wherein a pocket is formed into one of said first and second plastic sheets adjacent said monofilament line receiving slot wherein said cutting blade is received.

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 c ting tool of claim 1 wherein said flint 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 having a cylindrical section and annular walls extending radially therefrom for wrapping said monofilament line thereon.

6. The monofilament line cutting tool of claim 5 wherein a pocket is formed into one of said first and second plastic sheets adjacent said monofilament line receiving slot wherein said cutting blade is received.

8. The monofilament line cutting tool of claim 5 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.

9. The monofilament line cutting tool of claim 8 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

10. The monofilament line cutting tool of claim 9 wherein a pocket is formed into one of said first and second plastic sheets adjacent said monofilament line receiving slot wherein said cutting blade is received.

7. The monofilament line cutting tool of 6 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

11. 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;

a monofilament line receiving slot in said first and second plastic sheets extending to said cutting edge, said slot having a length and a width with said length being longer than said width and transverse to said cutting edge, whereby a monofilament line can be cut by bending into a U-shape and inserting the U-shape into the slot and contacting said cutting edge; and

,

wherein said first and second plastic sheets include shaped projections adjacent said cutting edge which together form a three dimensional space generally around said cutting edge with a portion of the cutting edge accessible for cutting the monofilament line, while the projections obstruct other access to the cutting edge.

12. The monofilament line cutting tool of claim 11 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

13. The monofilament line cutting tool of claim 11 wherein a pocket is formed into one of said first and second blade sheets adjacent said monofilament line receiving slot wherein said cutting blade is received.

14. The monofilament line cutting tool of claim 13 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

15. 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;

a monofilament line receiving slot in said first and second plastic sheets extending to said cutting edge, whereby a monofilament line can be cut by bending into a U-shape and inserting the U-shape into the slot and contacting said cutting edge;

wherein said first and second plastic sheet include shaped projections adjacent said cutting edge which together form a three dimensional space generally around said cutting edge with a portion of the cutting edge accessible for cutting the monofilament line, while the projections obstruct other access to the cutting edge; and

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 having a cylindrical section and annular walls extending radially therefrom for wrapping said monofilament line thereon.

16. The monofilament line cutting tool of claim 15 wherein a pocket is formed into one of said first and second plastic sheets adjacent said monofilament line receiving slot wherein said cutting blade is received.

17. The monofilament line cutting tool of claim 16 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

18. The monofilament line cutting tool of claim 15 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.

19. The monofilament line cutting tool of claim 18 wherein said first and second plastic sheets are thermally shaped and are bonded to each other by thermal welding.

20. The monofilament line cutting tool of claim 19 wherein a pocket is formed into one of said first and second plastic sheets adjacent said monofilament line receiving slot wherein said cutting blade is received.
