The crochet hooks were designed according to ergonomic considerations. The handle is made of TPE with a slightly roughened surface, so that the crochet hook can be held for longer comfortably, safely and without tiring. The shape of the crochet hook handle facilitates a relaxed and loose handling to support the fine motor movements when crocheting. The shaft and the outer face of the crochet hook are highly polished so that the tip glides smoothly through the loops. Thanks to a roughened chamfer (inside the hook) the yarn can be held more easily when the crochet hook is pulled back.
