The Osborne Automatic Awl Straight Needle #413N-8, at 2-1/8 inches, serves as a precise 14-gauge coarse straight needle with diamond point for sewing thick fabrics. This replacement needle pairs with the Osborne #413 Automatic Awl, handling coarse threads like waxed polyester on leather or canvas--think of its short straight design piercing where others falter, reviving your awl for reliable stitches in tough materials.
