(4) FIGS. 9-12 are an isometric perspective of the insertion wire and the retaining plate therefor of the threading aid of the present invention along with an end elevation, a side elevation and a plan view respectively.

(5) FIGS. 13-16 are an isometric perspective of the cutting blade of the threading aid of the present invention along with an end elevation, a side elevation and a plan view respectively.

(6) FIGS. 17-20 are an isometric perspective of the lower shell of the threading aid of the present invention along with an end elevation, a side elevation and a plan view respectively.

(7) FIGS. 21-24 are isometric perspectives of the upper shell, insertion wire and retaining plate therefor, the cutting blade and the lower shell of the threading aid of the present invention, disposed on the page so as illustrate the assembly thereof.

(8) In FIG. 1, threading aid 30 has planar threading ledge 32 formed in one end thereof with threading aperture 34 passing therethrough adjacent ridge 36 having wire aperture 38 therein adjacent threading aperture 34 with wire insertion loop 40 having angular return bend 42 formed therein with loop 40 extending over threading aperture 34. Thickened portion of threading aid 30 has grasping depression 44 formed therein with grip enhancing surfaces 46 defined therein in the form of protrusions 48 extending upwardly therefrom. Cutting aperture 50 is formed in the other end of threading aid 30.

(9) In FIG. 2, needle 52 having eye 54 formed therein has angular return bend 42 of wire loop 40 passing through eye 54 with needle 52 being urged toward ridge 36. Preferably wire loop 40 is comprised of annealed stainless steel wire having a diameter of less than about 0.25 mm, more preferably less than about 0.20 mm and most preferably about 0.15 mm. In FIG. 3, eye 54 of needle 52 has been passed inwardly toward ridge 36 allowing wire loop 40 to open so that thread 56 may pass through wire loop 40 and threading aperture 34. In FIG. 4, needle 52 has been passed outwardly away from ridge 36 over return bend so that thread 56 is now passing through eye 54 of needle 52. Preferably planar threading ledge 32, and most preferably the upper surface of threading aid 30 will be of a color contrasting with the color of wire loop 40. In the most preferred embodiment the entirety of threading aid 30 will be a color contrasting to the color of wire loop 40 to facilitate ready discernment thereof by the user.
