A massage for your hands! The combination of slightly rounded squared edges and a uniquely textured tip surface promotes positive ergonomics when in use – stimulating circulation and reducing tension.The needles sit perfectly in the hand and can be held effortlessly. This is especially beneficial to those who may struggle with grip issues such as arthritis, etc. More points of focus. The longer tapered Rocket points make sliding into the tightest or most intricate stitches a breeze. And, as with all addi circular needles, the transition from tip to cord is seamless thanks to precise German engineering and our perfectly pliable blue nylon cords. It’s all about the texture! Not only does the surface of the Rocket² promote comfort while knitting, users will quickly realize that stitches stay on the needle – where they belong (think of it as a no-slip tip). And, thanks to the texture’s spacing, you will experience perfectly even stitches every time. Please note that due to the innovative tip design, these needles are not compatible with existing addi needle gauges.
