crochetHow to choose a crochet hook
Choose diameter for the fabric, then choose a handle and head shape that fit how you work.

The diameter on the shaft matters more than the color or letter on the handle. Different brands can attach the same US letter to different diameters. If a pattern gives both a letter and millimeters, start with millimeters. Steel thread hooks have their own numbering system.
The label recommendation is a starting point. A tight fabric for a stuffed object and a draping garment can use different hooks with the same yarn. Work the pattern stitch in a swatch and compare the result before changing sizes.
Notice where loops sit
An inline head stays close to the shaft diameter, while a tapered style narrows toward the throat. That geometry changes how the yarn travels while you insert and draw through. It does not prove one hook will make better stitches for everyone.
Susan Bates Silvalume specifies an inline head and anodized aluminum. Clover describes Amour around loop handling and a shaped grip. If you frequently split yarn, check that the hook passes between complete strands, then try a different head shape in the same millimeter size.
Compare handle shape and weight
A cushion handle gives your fingers a larger area to rest on. A flat handle and a rounded handle locate the thumb differently. Try a relaxed pencil or knife grip and notice whether the handle presses into the palm. If the handle presses into your hand, try a different shape rather than gripping harder.
Furls Streamline Metal is solid aluminum with a substantially wider body and published size-dependent weight. That may appeal if you prefer weight in the hand; it is a different choice from a thin aluminum hook. Check the dimensions before buying a large set.
Buy sizes you will use
A set can be convenient for switching between swatches, but a large quantity of hooks is not itself a benefit. A fine-yarn set can omit the large diameter your blanket needs. Check each included size and whether scissors or needles are part of the package.
Tulip ETIMO Red covers smaller yarn-hook sizes. GRANDHOOK covers much larger 8–15 mm sizes. They are different tools for different fabric, even though both use cushion grips.
Keep steel thread hooks separate
Steel hooks are usually used with fine crochet thread and lace. A larger steel number commonly means a smaller diameter. Historic ordinary UK numbering also runs in reverse, but it is not the steel scale.
If the pattern says only “size 10,” identify the system before buying. Use the listed thread and gauge as context, then confirm millimeters on the package. The converter deliberately shows multiple possible diameters where numbering is inconsistent.
