The apparatus of claim 1, wherein the blade handle comprises: a first and second handle arm positioned substantially parallel to each other flexibly coupled to a common base. 8. The apparatus of claim 7, wherein the first and second arms flex altering the distance between them at the distal end from the base, this flexing allowing the handle arms to be placed in the cavity in the end surface of the blade. 9. The apparatus of claim 8, wherein a notch in the first and second arms of the handle engage the cavity of the blade when the flexing of the arms is released. 10. The apparatus of claim 7, wherein the first and second arms have a groove running along a length of a side for guiding the insert. 11. The apparatus of claim 10, wherein when the handle arms are engaged in the cavity of the blade, the insert can slide up the handle into a space in the cavity locking the handle firmly to the blade. 12. The apparatus of claim 1, wherein the blade handle comprises: a first and second handle arm positioned parallel to each other flexibly molded integrally to a common base. 13. The apparatus of claim 12, wherein the first and second arms flex altering the distance between them at the distal end from the base this flexing allowing the handle arms to be placed in the cavity in an end surface of the blade. 14. The apparatus of claim 13, wherein a notch in the first and second arms of the handle engage the cavity of the blade when the flexing of the arms is released. 15. The apparatus of claim 2, wherein the first and second arms have a groove running along a length of a side for guiding the insert. 16. The apparatus of claim 15, wherein when the handle arms are engaged in the cavity of the blade, the insert can slide up the handle into a space in the cavity locking the handle firmly to the blade. 17. The apparatus of claim 2, wherein at least one of the first end surface and the second end surface forms an oval thereof. 18. An apparatus comprising: a pedicure blade; a pedicure blade handle comprising a base and a pair of arm portions extending from the base the arm portions coupled to the pedicure blade; and a locking insert disposed between the arm portions of the handle such that the insert is slidable up and down at least a portion of an interior of the handle and in a first position coupled to the pedicure blade for releasably locking the handle to the blade, wherein the insert is removable from the handle. 19. A method comprising: flexing a pair of handle arms on a handle; positioning the pair of handle arms in a cavity in a pedicure blade; releasing the pair of handle arms from the flexed position; sliding an insert into the remainder of the cavity left by the handle arms; and locking the handle arms in place in the blade. 20. The method of claim 19, wherein flexing the pair of handle arms moves their ends away from one another. 21. The method of claim 19, wherein flexing the pair of handle arms moves their towards one another. 22. The method of claim 19, wherein the insert is removable from the handle. 23. An apparatus comprising: a pedicure blade having a cavity portion defined by an end surface thereof, a handle and an insert; means for engaging the cavity portion of the pedicure blade with the handle; and means for releasably locking the handle to the cavity portion of the blade. 24. The apparatus of claim 23, wherein the means for engaging the pedicure blade comprises: handle arms having notches disposed therein near a free end of handle arms for engaging the cavity of the blade. 25. The apparatus of claim 23, wherein the means for locking the handle to the blade comprises: moving the insert from an end of the handle near a base of the handle to an end of the handle opposite the base in contact with an end surface of the blade to prevent the handle arms from flexing. 26. An apparatus comprising: a pedicure blade; a pedicure blade handle comprising a base and a pair of arm portions
