Great needles for less hand fatigue and wear and tear hands. The square design of the needle shafts helps stop the needles from twisting and turning in your hands as you knit. But the greatest innovation with these needles is the new K-Kable that's different from any other cable on the market. Advertised that they won't kink, kurl or knot, these cables have virtually no memory, which means you don't have to worry about their getting stiff and out of shape when coiled for storage.
