The ChiaoGoo RED line of surgical-grade, stainless steel circulars have a nicely rounded but not too tapered tip, a smooth, satin-sheen finish and memory-free, multi-strand, steel cable coated with red nylon allowing yarn to slide right over. You can't overstate how good the cable is as it doesn't stick, twist or curl into an unmanageable lasso. You are definitely in control of this circular!
These ChiaoGoo Knit Red fixed circular needles have the purpose-built bent tips specifically designed for knitting in the round or circular knitting. The idea is that the bend orients the tip into a 'round' or tubular shape and that means that your wrists aren't constricted by having to bend inwards as much which makes for a more comfortable ergonomic knitting position.
The needle size is permanently laser imprinted on each circular and the precisely machined tips and joins are just spectacular. Stainless Steel - super glide!
