The finest needle in general use. Lace shawls and fine socks, worked at around 32 stitches to 10 cm — slow, and unforgiving of a dropped stitch.

Frequently asked questions
What is a 2 mm knitting needle in US and UK sizes?
US 0 and UK 14. The millimetre figure is the actual diameter and the only one that means the same thing everywhere.
Is a US 0 the same as a UK 0?
No. A US 0 is 2 mm; a UK 0 is 8 mm. The scales run in opposite directions — American numbers grow with the needle and British ones shrink — so the same number is two different needles.
What yarn suits a 2 mm needle?
Lace, 2-ply. The finest needle in general use. Lace shawls and fine socks, worked at around 32 stitches to 10 cm — slow, and unforgiving of a dropped stitch.
Why do the two scales run in opposite directions?
The British scale counts down from the thickest wire in a gauge, in the same way a wire gauge does — more drawing operations, higher number, thinner. The American scale simply counts up from the finest needle. Neither is wrong; they were never designed to be compared, and the only size where the numbers coincide is 4.5 mm, which is size 7 in both.
