Knitpicks makes these durable fixed circular needles in all the sizes and lengths that are not available as interchangeable circular needles. These classic circular needles have the same super flexible cable with secure and smooth cable to needle join, slick nickel-plated needle surface and tapered tips as the Knitpicks Options needles. The 40-inch needle tips are 5 1/8 inches long. Since the cable is super flexible, the Magic Loop method of sock knitting can be accomplished for two socks at a time with either the 40-inch or 47-inch needles.
The metric sizing system is more precise than the US sizing system. We offer two US size 1 - equivalent to 2.25mm and 2.50mm and two US size 2 - equivalent to 2.75mm and 3.00mm.
