Crochet Hook Anatomy

All crochet hooks feature the same parts in various forms:

  • Handle: The handle of a crochet hook is where you hold your crochet hook.
  • Thumb Rest or Grip: Depending on the type of crochet hook you have, this part of the hook is often shaped for you to either grip with your thumb pointy finger. Or created as a part where you rest your thumb. This can either be in metal or soft. In some cases you don’t have this part on your crochet hook.
  • Shaft: Also known as the shank. This part is between either the handle and the head or between the thumb rest/grip and the head. If you work with many loops, the yarn will slide back and forth on this area while you crochet.
  • Head or hook: The head or hook part of the crochet hook consists of many parts. The throat, bowl, lip and point. It looks different depending on if you have a inline crochet hook, tapered crochet hook or hybrid crochet hook.

What Is An Inline Crochet Hook?

An inline crochet hook is defined by the fact that the the head of the crochet hook is aligned with the shaft.

What Is A Tapered Crochet Hook?

With a tapered crochet hook the final part towards the head is not aligned with the rest of the hook, but have a slight curve inwards towards the hook part.

Materials Crochet Hooks Are Made Of

There are a few different types of crochet hooks available on the market from different manufacturers, and each has its own advantages and disadvantages.

Another popular option is the plastic hook, which is often less slippery than metal but not as strong.

Finally, there are bamboo and wooden hooks, which are both great options.

Common materials include aluminum.

Aluminum hooks are known for its lightweight feel and smooth glide through yarn; steel is ideal for fine crochet work with crochet thread or lace weight yarn due to its precise hook; plastic offers affordability, lightweight, and gentle handling, making it suitable for beginners or those with hand sensitivity.

    Longest Crochet Marathon

    The next crochet world record is one that if it wasn’t recorded, I wouldn’t believe it.

    The longest crochet marathon is an astonishing 72 hours. As much as I love to crochet I don’t think I could ever crochet for 72 hours straight.

    This record was achieved by a Nigerian woman from December 24 – 27, 2023. The previous record was thirty-four hours and seven minutes.

    When asked why she decided to attempt this record she said that it stemmed from her passion for crochet and that she wanted to push her personal limits. She also said:

    I aim to showcase the artistry and perseverance involved in this craft and promote awareness about crocheting and its benefits.

    During her crochet marathon she created a white dinner gown and was only allowed to rest for two hours of rest, five minutes for each hour of crochet. During these breaks she could eat, sleep, go to the bathroom or change her clothes.

    This is amazing on so many levels. I love that she combined her love of the craft while at the same time challenging herself. Her desire to bring attention to how wonderful crochet is makes me a little verklempt.
