The invention claimed is: 1. A tether, comprising: a. an elastic member having an unstretched length disposed between a first end and a second end which includes a first portion of said unstretched length which has a first amount of elastic resistance and a second portion of said unstretched length

The invention claimed is: 1. A tether, comprising: a. an elastic member having an unstretched length disposed between a first end and a second end which includes a first portion of said unstretched length which has a first amount of elastic resistance and a second portion of said unstretched length which has a second amount of elastic resistance, and wherein said first portion of said unstretched length provides less elastic resistance than said second portion of said unstretched length; b. a flexible member disposed between a first end and a second end having less elasticity than said elastic member which limits stretched length of said elastic member; and c. a first fastener and a second fastener each coupled to a corresponding one of said first end and said second end of said elastic member and to a corresponding one of said first end and said second end of said flexible member. 2. A tether as described in claim 1, wherein said first portion of said unstretched length and said second portion of said unstretched length comprise a first discrete elastic element having said first amount of elastic resistance joined to a second discrete elastic element having said second amount of elastic resistance. 3. A tether as described in claim 2, wherein said first portion of said unstretched length and said second portion of said unstretched length comprises a first discrete elastic element having said first amount of elastic resistance joined to at least two elastic elements having a combined elastic resistance which comprises said second amount of elastic resistance. 4. A tether as described in claim 3, wherein said at least two elastic elements having said combined elastic resistance comprises a plurality of layers of said first elastic element. 5. A tether as described in claim 4, wherein said plurality of layers of said first elastic element comprise a folded portion of said first elastic element. 6. A tether as described in claim 5, wherein said folded portion of said first elastic element comprises three layers of said first elastic element. 7. A tether as described in claim 6, wherein said first elastic element comprises an elastic strap. 8. A tether as described in claim 1, wherein said first portion of said unstretched length and said second portion of said unstretched length comprises said unstretched length of said elastic member having lesser elastic resistance proximate to said first end and greater elastic resistance proximate to said second end. 9. A tether as described in claim 1, wherein said first end and said second end of said flexible member have correspondingly fixed engagement proximate to said first end and said second end of said elastic member. 10. A tether as described in claim 1, wherein each of said first fastener and said second fastener provides a base coupled to a corresponding one of said first end and said second end of said elastic member and a clasp coupled to said base. 11. A tether as described in claim 1, wherein said first fastener comprises a ring element coupled to said first end of said elastic member and said flexible member, and wherein said second fastener comprises a tool containment element coupled to said second end of said elastic member and said flexible member. 12. A method for producing a tether, comprising the steps of: a. providing an elastic member having an unstretched length disposed between a first end and a second end including: i. providing a first portion of said unstretched length having a first amount of elastic resistance; ii. providing a second portion of said unstretched length having a second amount of elastic resistance, wherein said first portion of said unstretched length provides less elastic resistance than said second portion of said unstretched length; b. coupling a first fastener to said first end of said elastic member; and c. coupling a second fastener to said second end of said elastic member. 13. A method for producing a tether as described in claim 12, wherein said step of providing a first portion of said unstretched length having a first amount of elastic resistance comprises the step of providing a first discrete elastic element having a first amount of resistance. 14. A method for producing a tether as described in claim 13, wherein said step of providing a second portion of said unstretched length having a second amount of elastic resistance comprises the step of providing a second discrete elastic element having said second amount of resistance, and wherein said first discrete elastic element having said first amount of elastic resistance connects to said second discrete elastic element having said second amount of elastic resistance to form said elastic member. 15. A method for producing a tether as described in claim 12, wherein said step of providing a first portion of said unstretched length having a first amount of elastic resistance comprises the step of providing an elastic element having an unstretched length disposed between a first end and a second end, and wherein said step of providing a second portion of said unstretched length having a second amount of elastic resistance comprises the step of folding a portion of said unstretched length of said elastic element to generate at least two layers. 16. A method for producing a tether as described in claim 15, wherein said step of coupling a first fastener to said first end of said elastic member comprises the step of coupling a base to said first end of said elastic member and a clasp coupled to said base. 17. A method for producing a tether as described in claim 16, wherein said step of coupling a second fastener to said second end of said elastic member comprises the step of coupling a tool containment element to said second end of said elastic member and said flexible member. 18. A method for producing a tether as described in claim 12, further comprising the step of providing a flexible member disposed between said first end and said second end having less elasticity than said elastic member which limits stretched length of said elastic member. 19. A method for producing a tether as described in claim 18, where said step of providing a flexible member disposed between said first end and said second end having less elasticity than said elastic member which limits stretched length of said elastic member further comprises locating said elastic member having an unstretched length disposed between a first end and a second end within said flexible member.
