The subassembly of claim 4 wherein said first spring includes an abutment shoulder and said first flange has a first end and a second end, said second end of said first flange facing toward and being located nearer said second end of said first frame side member than said first end of said first frame side member yet being spaced far enough from said spring retainer to permit said first spring to be inserted between said second end of said first flange and said spring retainer and to permit said hook portion to be placed into engagement around said spring retainer and said shoulder to be placed into engagement with said first end of said first flange during installation of said first spring with respect to said first frame side member.
- 9. The subassembly of claim 1 further comprising a handle including a second frame side member spaced apart from said first frame side member.
- 10. The subassembly of claim 9, wherein said first flange extends between said first frame side member and said second frame side member.
- 11. The subassembly of claim 10 wherein said first flange is interconnected with said second frame side member, said first and second frame side members and said first flange defining a central channel, and said first spring being located within said central channel.
- 12. The subassembly of claim 10 wherein said second frame side member is substantially parallel to said first frame side member.
- 13. The subassembly of claim 11 wherein said central channel is capable of receiving said first tool member.
- 14. The subassembly of claim 13 wherein said central channel is capable of receiving a second tool member.
- 15. The subassembly of claim 11 further including two or more tool members, each of said tool members having a base in contact with one or more springs.
- 16. The subassembly of claim 1 wherein said first tool member is a first one of a pair of plier jaws.
- 17. The subassembly of claim 1 wherein said first tool member is a first one of a pair of scissors.
- 18. The subassembly of claim 1 wherein said first spring includes a shoulder engagable with said first flange to restrict longitudinal movement of said first spring with respect to said first frame side member.
- 19. The subassembly of claim 1 further including a second spring resting against said first flange.
- 20. The subassembly of claim 1 wherein said first spring extends longitudinally along said first frame side member.
- 21. The subassembly of claim 1 wherein said first spring is substantially the same length as said first frame side member.
- 22. The subassembly of claim 1 wherein said first spring is restrained from longitudinal movement in one direction by said spring retainer and retained from longitudinal movement in the opposite direction by said first flange.
- 23. A subassembly of a folding tool, comprising:(a) a first tool member having a base; (b) an elongate, first frame side member having an upper edge and a spring stop extending laterally from said upper edge; (c) a first pivot axle extending transversely with respect to said first frame side member, said first tool member being pivotably mounted on said first pivot axle; d) an elongate, longitudinally extending first spring having a resilient tip at one end, a hook at a longitudinally opposite end and a middle portion having a back; and e) a spring retainer extending transversely with respect to said first frame side member, said first spring being arranged with said tip pressing on said base of said first tool member, said hook extending at least partially around said spring retainer, and said back resting against said spring stop, and wherein said spring stop is engaged with said back and thereby prevents longitudinal movement of said first spring toward said spring retainer.
- 24. The subassembly of claim 23 wherein said first pivot axle and said first tool member are located substantially at a first end of said first frame side member and said spring retainer is located substantially at a second, longitudinally opposite, end of said first frame side member.
- 25. The subassembly of claim 23 wherein said spring retainer is a second pivot axle.
- 26. The subassembly of claim 23 wherein said spring stop is a flange, integral with said first frame side member and extending laterally therefrom.
- 27. The subassembly of claim 23 further including a second frame side member spaced apart from said first frame side member.
- 28. The subassembly of claim 23 wherein said first spring is substantially the same length as said first frame side member.
- 29. The subassembly of claim 23 wherein said spring retainer restrains axial movement of said first spring in one longitudinal direction and engagement of said first spring with said spring stop restrains axial movement of said first spring in an opposite direction.
- 30. The subassembly of claim 27 wherein said first flange extends toward said second frame side member, substantially defining a channel.
- 31. The subassembly of claim 27 wherein said first flange joins said first and second frame side members.
- 32. The subassembly of claim 27 wherein said first flange is also integral with said second frame side member.
- 33. A method of assembling a tool of the type having:a first tool member having a base; an elongate first frame side member having an upper longitudinal edge and a spring stop extending laterally from said upper edge of said first side frame member; a first pivot axle capable of rotatably mounting said first tool member to said first frame side member; an elongate, longitudinally extending first spring having a resilient tip at one end, a hook at the longitudinally opposite end, and a middle portion having a back; and a spring retainer extending transversely with respect to said first frame side member, said method comprising: (a) engaging said spring retainer with said first spring by placing said hook of said first spring at least partially around said spring retainer; (b) thereafter, positioning said spring with respect to said first frame side member by rotating said spring around said spring retainer until said back of said first spring is against said spring stop; (c) rotatably attaching said first tool member to said first frame side member by passing said first pivot axle through aligned bores formed respectively in said base of said first tool member and said first frame side member; and (d) operatively engaging said base of said first tool member with said first spring by urging said first spring against said spring stop and into a flexed condition and thereafter aligning said base of first tool member with said resilient tip of said first spring while keeping said first spring flexed.
- 34. The method of claim 33 wherein said spring stop comprises an integral flange extending laterally from said upper edge of said first frame side member.
- 35. The method of claim 33 where in said spring stop and said spring retainer define an opening therebetween, said method including engaging said spring retainer with said first spring by passing said first spring through said opening until said spring retainer is at least partially received in said hook.
