Abstract
Abstract An animal leash including an elongated leather strip on which there is sewn a transparent polyvinyl chloride strip having a prism design on one surface thereof and an opaque polyvinyl chloride strip secured to the one surface of the transparent strip. The combined polyvinyl chloride strips are sewn to the leather strip resulting in a leash having a light reflective surface. The areas around the stitching are crimped thereby increasing the reflecting angle of the polyvinyl chloride.
