1. An instrument for insertion of an implant comprising a shaft defining a longitudinal axis, the shaft having a distal tip and a flexible portion proximal to the distal tip, wherein the flexible portion includes a series of discrete, interlocking segments along the longitudinal axis, each of the discrete, interlocking segments having a base and a series of identically shaped protrusions extending therefrom around the longitudinal axis, a first portion of a first protrusion of the series of protrusions of each of at least three of the discrete, interlocking segments being at a first circumferential position about the longitudinal axis, each of the first portions extending a maximum distance in a first direction from the respective base of the discrete, interlocking segments that is different than a maximum distance the others of the first portions of the first protrusions of the at least three discrete, interlocking segments extend in the first direction from their respective bases. 2. The instrument of claim 1, wherein the discrete, interlocking segments are constructed from a solid, continuous length of material by a plurality of cuts. 3. The instrument of claim 2, wherein the plurality of cuts extend completely through the thickness of the shaft of the instrument. 4. The instrument of claim 3, wherein the plurality of cuts are laser cuts shaped like jig saw puzzle pieces such that adjacent discrete, interlocking segments interlock with one another. 5. The instrument of claim 1, wherein the shaft of the instrument is constructed from a material comprising hypodermic tubing, polymer, or stainless steel. 6. A system comprising: an implant; andthe instrument of claim 1, wherein the instrument further includes a proximal handle, and the instrument is cannulated from the distal tip through the proximal handle such that suture, secured to the implant, extends through the cannulation from the implant and through the proximal handle. 7. The system of claim 6, wherein the distal tip of the shaft includes at least three prongs extending distally to define recessed areas for insertion of the implant therein. 8. The instrument of claim 1, wherein the distal tip includes prongs defining at least one recessed area having a u-shaped profile when viewed in at least one orientation perpendicular to a longitudinal axis of the instrument. 9. The instrument of claim 1, wherein the distal tip includes at least three circumferentially spaced-apart prongs, the prongs defining recessed areas for insertion of the implant therein. 10. A system for insertion of an implant comprising: the instrument of claim 1; andan implant received in the distal tip. 11. The system of claim 10, wherein the distal tip of the shaft includes at least three prongs extending distally to define recessed areas for insertion of the implant therein. 12. The instrument of claim 1, wherein the distal tip of the shaft includes at least three prongs extending distally to define recessed areas for insertion of the implant therein. 13. The instrument of claim 6, wherein the implant is a suture anchor, and wherein the flexible portion has a strength sufficient to insert the implant in the hole in bone. 14. The instrument of claim 1, wherein the at least three discrete, interlocking segments having the first portions of the first protrusions of the series of protrusions are adjacent to each other. 15. An instrument for insertion of an implant in a hole in bone, comprising: a distal tip;a proximal handle; anda shaft extending between the distal tip and the proximal handle and having a flexible portion,wherein the flexible portion includes a series of discrete, interlocking segments along a longitudinal axis of the flexible portion, each of the discrete, interlocking segments having a base and a series of identically shaped protrusions extending therefrom around the longitudinal axis, a first portion of a first protrusion of the series of protrusions of each of at least three of the discrete, interlocking segments being at a first circumferential position about the longitudinal axis, each of the first portions extending a maximum distance in a first direction from the respective base of the discrete, interlocking segments that is different than a maximum distance the others of the first portions of the first protrusions of the at least three discrete, interlocking segments extend in the first direction from their respective bases, andwherein the distal tip includes at least three prongs extending distally, the prongs defining recessed areas for insertion of the implant therein. 16. The instrument of claim 15, wherein the shaft also has a solid portion laser welded to the flexible portion. 17. The instrument of claim 15, wherein the implant is a suture anchor, and wherein the flexible portion has a strength sufficient to insert the suture anchor in the hole in bone. 18. The instrument of claim 15, wherein the discrete, interlocking segments and the distal tip are constructed from a solid, continuous length of material, at least the discrete, interlocking segments being constructed by a plurality of cuts extending completely through the thickness of the shaft of the instrument in the form of jig saw puzzle pieces such that adjacent discrete, interlocking segments interlock with one another. 19. The instrument of claim 15, wherein the at least one of the recessed areas has a u-shaped profile when viewed in at least one orientation perpendicular to a longitudinal axis of the instrument. 20. A system for insertion of an implant comprising: the instrument of claim 15; andan implant received in the recessed areas. 21. The instrument of claim 15, wherein the at least three discrete, interlocking segments having the first portions of the first protrusions of the series of protrusions are adjacent to each other.
