Crochet hooks come in all shapes and sizes to accommodate yarns ranging from delicate lace to super-thick jumbo weights. Each yarn requires a different hook size, and some patterns call for bigger hooks to create different textures - it’s important you select the right hook for the job. Explore our handy guide to help you select a hook that is compatible with your yarn weight and project!

Crochet hooks explained

The crochet hook is a sleek tool that comes in many shapes, sizes, and materials in order to best suit your needs and preferences. Let’s look at the anatomy of the hook:


Sharp points, particularly with steel crochet hooks, are good for intricate patterns where you might need to be carrying more than one stitch on your hook to create a motif.

Smooth rounded points (or head) are the perfect when working with yarns prone to splitting, or fashion yarns that have a deep halo or texture.


The throat of your hook will either be tapered or inline. Inline throats are steep and straight, and can help with keeping your stitches uniform, whereas tapered throats have a smooth slope and it can be easier for your stitches to slide across. The style you choose is all about preference – what suits your hand, and the action of how you work your stitches. Try both and see what suits you best!


The shaft can vary in length, depending on the depth of the handle. Long shafts provide enough length to work a multitude of stitch loops at once, such as cluster stitches and bobbles.

Thumb rest and handle

The thumb rest is the flattened widened indentation between the shaft and the handle. This is the part of your crochet hook which allows you to hold and manipulate the movement of your hook.

Hook materials

Bamboo and wooden

Crochet hooks made from wood and bamboo are perfect when working with yarns that tend to slip such as silk and mercerized cotton. Crocheters who suffer with pain in their hands and fingers often find bamboo and wooden hooks more comfortable to work with.


Light in the hand and smooth, aluminium hooks are particularly useful for yarns with a halo, or yarns that are sticky. They are cool to hold, and the speediest hook to use, but they can be slippery for a beginner.

Plastic and nylon

Plastic and nylon crochet hooks are gentler on the hand than metal, and give ease and comfort to crocheters who might suffer from arthritis or carpal tunnel syndrome. As well as gripping slippery yarn, plastic and nylon hooks are often created with an inbuilt flexible core for extra strength.

Types of crochet hook


Ergonomic crochet hooks are specifically designed for crocheters who experience discomfort or pain in their hands and fingers. For maximum comfort and ease, ergonomic hooks have specially designed handles for grip and can vary in size from basic projects to intricate advanced work.


Standard crochet hooks encompass bamboo, wooden, plastic, nylon and aluminum. Deciding which hook is best for your project may depend on the yarn, design or even personal preference.


Knooks (pronounced ‘nook’) are the hybrid between a knitting needle and a crochet hook, crocheting material that has a knitted texture.


The Tunisian crochet hook, is a long hook usually with a stop at one end, and hook on the other. The elongated body of the hook means that you can have many stitches on your hook at once, similar to knitting.
