The smooth cable join lets your stitches slide around your knitting needles with no snags. The long threaded join along with the tightening hole make for extra security that the cables and tips of the knitting needles will stay connected. And the flexible cable has very little memory so you can start knitting immediately. Simply unscrew the needle tips and screw on the cable caps to keep your knitting safe when your needle tips are required elsewhere. Lace knitters will love that they can tie a piece of scrap yarn through the tiny hole in the cable end (used for the tightening key) and thread a lifeline through their lace at regular intervals while they are knitting. Set includes one cable, two end caps and tightening key.
