The invention claimed is: 1. A spring-loaded case hook, the spring-loaded case hook comprising: a handle; a spring casing engaged to said handle, said spring casing having a hook end and a handle end; a hook having a shaft, a portion of said shaft being disposed in said spring casing; a stop engaged to said hook, said stop being constructed and arranged for positioning in said spring casing, said stop and said portion of said shaft being constructed and arranged for slidable positioning within said spring casing; at least one first spring disposed in said spring casing, said spring disposed about a portion of said shaft, said spring comprising a first end and a second end, said first end being proximate to said stop; and at least one second spring disposed in said spring casing, said at least one second spring disposed about a portion of the shaft, and wherein the second spring has a first end and a second end, the first end of the second spring engaged by the second end of the first spring. 2. The spring-loaded case hook of claim 1 wherein said at least one first spring is a progressive spring. 3. The spring-loaded case hook of claim 2 wherein said at least one first spring has a spring rate which increases with increasing deflection. 4. The spring-loaded case hook of claim 2 wherein said at least one first spring has a progressive spring rate of about 40 to about 150 pounds at 15% deflection. 5. The spring-loaded case hook of claim 2 wherein said at least one first spring has a progressive spring rate of about 60 to about 140 pounds at 15% deflection. 6. The spring-loaded case hook of claim 2 wherein said at least one second spring is a progressive rate spring. 7. The spring-loaded case hook of claim 6 wherein said at least one second spring has a progressive spring rate of about 30 to about 100 pounds at 25% deflection. 8. The spring-loaded case hook of claim 6 wherein said at least one second spring has a progressive spring rate of about 40 pounds to about 90 pounds at 25% deflection. 9. The spring-loaded case hook of claim 6 wherein said at least one second spring has a progressive spring rate that is less than that of said at least one first spring. 10. The spring-loaded case hook of claim 1 wherein said at least one first spring is chrome silicon steel. 11. The spring-loaded case hook of claim 1 the first end of said first spring being engaged by said stop. 12. The spring-loaded case hook of claim 1, the second end of the second spring being engaged by the inner surface of the casing at the hook end of the casing. 13. The spring-loaded case hook of claim 1 wherein said handle is non-rotatable relative to said casing. 14. The spring-loaded case hook of claim 1 wherein said casing has an inner surface and an outer surface and said outer surface of said casing is rectangular. 15. The spring-loaded case hook of claim 14, said shaft of said hook having a first end and a second end, the first end proximate the handle of the spring-loaded case hook and a bolt is non-rotatably engaged to said first end of said shaft. 16. The spring-loaded case hook of claim 1, said spring-loaded case hook has an overall length of about 25" (63.5 cm) to about 35" (about 90 cm). 17. The spring-loaded case hook of claim 1 wherein said handle has a gripping portion which is cylindrical and has a diameter of about ��" to about 1��". 18. The spring-loaded case hook of claim 1 wherein said stop is a nut. 19. A spring-loaded case hook, the spring-loaded case hook comprising: a handle; a rectangular spring casing engaged to said handle, said spring casing having an inner surface and an outer surface, and a hook end and a handle end and said spring casing is non-rotatable relative to said handle; a hook having a shaft, a portion of said shaft being disposed in said spring casing; a stop engaged to said hook, said stop being constructed and arranged for positioning in said spring casing, said stop and said portion of said shaft being constructed and arranged for slidable positioning within said spring casing; and at least one first progressive spring disposed in said spring casing and at least one second progressive spring disposed in said spring casing, said at least one first spring is disposed about a portion of said shaft and said at least one second spring is disposed contiguously with said at least one first spring about a portion of said shaft, said at least one first spring comprising a first end and a second end and said at least one second spring comprising a first end and a second end, said first end of said at least one first spring being proximate to said stop and said second end of at least one second spring being proximate said hook end of said casing. 20. The spring-loaded case hook of claim 19 wherein said at least one first progressive spring has a compression which is either less than or greater than said at least one second progressive spring.
