Square shape is ergonomic Unique swivel-join on firm cables mean your large projects don’t crimp Precise tips are sharp, but not too pointy Needle sizes are etched on, no need for a gauge! Lifetime warranty A square needle decreases contact stress by giving your fingers a flat surface to rest on while knitting. This is different from a traditionally-shaped round needle, which forces your fingers to rest on a smaller, convex-shaped surface area. This tension caused by a round needle can result in poor circulation and impaired nerves. Eliminating or reducing contact tension (by using a Square needle) can significantly reduce pain. We’ve had a number of customers tell us that they had stopped knitting until they discovered Kollage Square Knitting Needles! Square needles are perfect for knitters who have arthritis, carpal tunnel or stiffness in their wrists and fingers. Squares are designed to decrease pain and tension for those who love to knit. As a knitter, your hands are your most valuable tool!
