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. It won't kink and once removed from a package or pocket, it quickly straightens out--no retaining the coiled shape!
The 16" length (tip-to-tip measurement) is a good choice for baby sweaters, hats, and collars.
