The grip body includes: a base-end portion 5 which has substantially uniform in its section taken in a vertical direction to a longitudinal axis of the grip body; and a grip portion 6 which is formed on a tip-end side of the base-end portion and formed with a recess 7 on a side in its outer circumference. The recess is formed on a side where the hook portion has a catching head 8. The recess has an arc-like section, with a longitudinal center region being sunken. The crochet-hook shaft has its tip shifted to a side away from the side formed with the recess.
