Anatomy of a Crochet Hook
A crochet needle consists of 7 parts that are distributed in head and body. Each part of a crochet hook performs a specific function.
It is the tip of the crochet hook that is used to insert the hook into previously made stitches. Points can range from very rounded to very sharp. If the tip of the hook is too blunt, it makes it hard to get into the stitches. If it is too pointy, it will tend to split the yarn when inserting the hook. The easiest hook to work with is one that is semi-blunt.
It is the actual hook of the crochet hook. Is always better a rounded lip because a pointy one tends to snag on the stitches.
It can be either straight or rounded. The rounded one holds the yarn better.
It does the actual hooking of the yarn and pulls it through a stitch. It must be large enough to grab the yarn but small enough to prevent the previous loop from sliding off.
This part holds the loops that you are working with, and its diameter determines the size of the stitches. A hook with a large shaft makes easy create stitches that require many loops, like multiple stitches or cluster.
It is the part of the hook where you will rest your thumb while crocheting. It helps to keep the hook positioned in the right direction, letting easily rotate the hook with each stitch. Not all crochet hooks have a thumb rest.
It is used to balance and manoeuvre the crochet hook properly. The handle is the bit that will rest in your palm if you have a knife-grip, or against your index finger if you have a pencil-grip.
Crochet Hook Materials
In ancient times you could find crochet hooks made of bone, porcupine feathers, celluloid, agate and ivory. Luckily, nowadays, there are different materials!
The choice of material depends on the diameter of the hook, however, these limits are approximate. And except the smaller hooks, which are invariably made of steel, other materials may be found outside this range.
Crochet hooks are currently produced in diameters ranging from 0.25 mm to 25 mm. And the most common materials according to their thickness are the following:
Crochet hooks under 2.0 mm are made of steel, for its strength.
Aluminium is the predominant material from 2.0 mm to 6.0 mm, for its lighter weight.
Beyond 6.0 mm, bamboo, wood, and plastic are the more common materials, for their even lighter weight.
