Some of us here can't stop raving about the ChiaoGoo Red Lace needles. The tips are stainless steel with sharp points and the join to the cable is very smooth. But what sets it apart from other circular needles is the cable. It is a multi-strand steel cable coated with nylon. This makes it firm but flexible and it just won't kink!
The 32" (measured tip to tip) is often used for adult sweaters, baby blankets, shawls, and for picking stitches up for button bands.
