ChiaoGoo's newest square, stainless steel interchangeable tips (available in both 4-inch and 5-inch lengths) in sizes US3 – 11 and compatible with all ChiaoGoo small [S] and large [L] join interchangeable cables. These are more comfortable to hold than round needles due to the flat sides and rounded corners. Encounter less hand, wrist, finger, and even shoulder strain due to a more secure grip allowing for a more relaxed experience. Tightening and loosening the connection is also easier because of the flat sides. Made with the same hypoallergenic stainless steel and point design, the QUADS have the same weight and yarn glide as the round TWIST tips. Known to improve your stitch definition and uniformity. Calibrated to obtain the same gauge as when knitting with the same size round tips. Unlike other square-shaped needles, there is no need to “size up” to get the right gauge.
