Knit Pro says Cubics needles have a “unique ergonomic shape that provides comfort to the hand and yields uniform stitch formation.”
The cuboid shape in square cross-section gradually gives way to perfectly tapered needle points. Their polished wood surface works effortlessly with every type of yarn without slowing down knitting rhythm. Also, being made from Symfonie rose wood, they are lightweight in addition to being strong and flexible. This flexibility is why they’re recommended for those with arthritis problems or repetitive stress injuries.
