The pull-through needles made of hardened steel or refined brass are suitable for pulling elastic bands and cords through waistbands, hoods, etc. The brass version is a needle with a split shaft and open towards the eye, with the needle tip being spherically rounded. If you thread a band into this eye and then pull it down between the halves of the needle shaft, it gets caught and can then be pulled through the tunnel securely anchored. The other pull-through needle, made of rustproof steel, is also a blunt needle. However, it has a wide, flattened and therefore thinner needle shaft with a long and a round eye. The long eye is intended to hold ribbons and thick threads, the round one is suitable for finer threads and round elastics. The burr-free, rounded tips of the needles cannot pierce through the fabric and therefore slide easily through any tube of fabric. The well-balanced spring stiffness and smooth coated surface make these needles professional tools.
