The Ballpoint needle has a rounded, semi-spherical ball point whose diameter is approximately 20% of the blade's diameter. These needles are designed to alleviate making holes in knit or loosely woven materials. The rounded tip slips between yarns rather than piercing them.
Ballpoint Needles are available in sizes 70/9 (Art. No 9126), 80/11 (Art. No 9127), 90/14 (Art. No 9128), 100/16 (Art. No 9129).
