HiyaHiya, 16" Steel SHARP Circular Needle: US 9 (5.5mm)
With flexible cables and smooth joins, this lightweight stainless steel circular needle allows stitches to slip easily off, and is a great addition to any knitter's toolbox. This SHARP line is quite suitable for intricate needlework with lots of increases, decreases and yarn overs. Also good for fine, densely plied yarn like sock yarn.
This 16" length is widely used for child and adult hats, baby cardigans, sweater collars and other projects with a medium circumference.
