addi Turbos are perhaps the most recognized name in knitting needles. The slick, nickel-plated finish makes stitches glide, and the pliant, blue cord resists kinks and curls. The original Turbo tip is slightly blunter than the Lace or Rocket tips, which makes it ideal for working with yarns that have a tendency to split. The unique EasyKnit design features one tip that is longer than the other to more easily facilitate working in the round at small circumferences.
