Abstract: An adjustable length circular knitting needle assembly includes a pair of knitting needles having distal pointed ends and a cord extending between the proximal ends thereof. At least one of the needles is provided with a hollow tubular portion which houses a reel assembly to which one end of the cord is secured. The reel assembly includes a distal idler wheel and a proximal spool wheel, and an endless belt secured therebetween. The cord passes through the tubular portion and is secured to the endless belt. A folding tab handle is joined to the spool wheel shaft to rotate the spool wheel and drive the belt, permitting the cord to be taken up or released as desired. A slot or window is provided in the tubular portion to permit access to the tab handle without disassembly of the needle.
