This is a high quality, smooth, 25mm wooden (birch) crochet hook. The ergonomic design includes a thumb rest for a comfortable grip while crocheting - this helps reduce tension in your hands. So, whether it's a Butter Knife Hold, Saber or Pencil Grip, this lovely hook will make your chunky yarn projects more enjoyable. The hook is approx. 20cm (200mm) long and is great for crocheting with bulky yarns, like the t-shirt yarn and braided macramé cords that you can find on our store.
