Abstract

A tool and a method of manufacture of the tool are provided. The tool is prepared by the steps of providing a first tool half having a first jaw, providing a second tool half having a second jaw, inserting a temporary sleeve through an opening in the first tool half, the temporary sleeve having an opening configured to receive an end of a biased member that extends axially, aligning the end of the biased member with the opening in the first tool half, disposing the biased member within a cavity formed by the first tool half and the second tool half, and removing the temporary sleeve.

First claim

What is claimed is:

1. A method of manufacturing a plier, the method comprising:
providing a first tool half having a first jaw;
providing a second tool half having a second jaw;
machine matching the first tool half to the second tool half;
inserting a temporary fastener through openings in the first tool half and the second tool half, the temporary fastener configured to couple the first tool half to the second tool half;
heat treating the first tool half and the second tool half; and
subsequent to the heat treating, removing the temporary fastener and inserting a permanent fastener.

2. The method of manufacturing a plier of claim 1 , further comprising deforming an end of the permanent fastener to couple the first tool half to the second tool half.

3. The method of manufacturing a plier of claim 2 , further comprising grinding smooth the deformed end of the permanent fastener.

4. The method of manufacturing a plier of claim 3 , further comprising polishing the coupled first tool half and second tool half.

5. The method of manufacturing a plier of claim 4 , further comprising attaching grips to each of the first tool half and the second tool half.

6. The method of manufacturing a plier of claim 5 , where the attaching the grips to each of the first tool half and the second tool half further comprises coagulating a polymer coating onto the first and second tool halves.

7. The method of manufacturing a plier of claim 1 , further comprising not hardening the permanent fastener by heat treatment.

8. A method of manufacturing a tool, the method comprising:
providing a first tool half having a first jaw;
providing a second tool half having a second jaw;
inserting a temporary sleeve through an opening in the first tool half, the temporary sleeve having an opening configured to receive an end of a biased member that extends axially;
aligning the end of the biased member with the opening in the first tool half;
disposing the biased member within a cavity formed by the first tool half and the second tool half; and
removing the temporary sleeve.

9. The method of manufacturing a tool of claim 8 , where the end of the biased member comprises a first end, and where the method further comprising inserting a second end of the biased member that extends axially into an opening in the second tool half prior to receiving the first end into the temporary sleeve.

10. The method of manufacturing a tool of claim 9 , further comprising coupling the first tool half with the second tool half with a permanent fastener.

11. The method of manufacturing a tool of claim 10 , further comprising deforming an end of the permanent fastener to secure the first tool half to the second tool half.

12. The method of manufacturing a tool of claim 11 , further comprising grinding smooth the deformed end of the permanent fastener.

13. The method of manufacturing a tool of claim 9 , further comprising heat treating the first tool half and the second tool half.

14. Pliers prepared by a process comprising the steps of:
providing a first tool half having a first jaw;
providing a second tool half having a second jaw;
inserting a temporary sleeve through an opening in the first tool half, the temporary sleeve having an opening configured to receive an end of a biased member that extends axially;
aligning the end of the biased member with the opening in the first tool half;
disposing the biased member within a cavity formed by the first tool half and the second tool half; and
removing the temporary sleeve.

15. The pliers of claim 14 , where the end of the biased member comprises a first end, and where the steps further comprise inserting a second end of the biased member that extends axially into an opening in the second tool half prior to receiving the first end into the temporary sleeve.

16. The pliers of claim 15 , where the steps further comprise coupling the first tool half with the second tool half with a permanent fastener.

17. The pliers of claim 16 , where the steps further comprise deforming an end of the permanent fastener to secure the first tool half to the second tool half.

18. The pliers of claim 17 , where the steps further comprise grinding smooth the deformed end of the permanent fastener.

19. The pliers of claim 15 wherein the biased member biases the first tool half with respect to the second tool half by applying a biasing force on the opening in the first tool half and the opening in the second tool half.

20. The pliers of claim 14 , where the steps further comprise heat treating the first tool half and the second tool half.
