Pony Interchangeable Circular Knitting Needle Shanks - a brilliant way to get all the sizes you need for every project imaginable! Made from lightweight bamboo, every set of Pony shanks is smooth and finely tapered to make for a gentle knitting experience without the risk of snagging. Attach to different length cables for different size projects; swap midway to a larger size needle for tighter edges; stop altogether and take a break from your current project; whatever you feel like doing, interchangeable needles give you the freedom and flexibility to be creative in your own way. With cables available in sizes 40, 60, 80, 100, and 120cm you can mix and match your way to the perfect needle set.
