Knitting Needles
Knitting needles are the main tool of knitting, available as straight needles, circular needles, and double-pointed needles, in materials like wood, metal, and plastic.
Explanation
Knitting needles are the fundamental tool of knitting, and come in three main types: straight needles for flat knitting, circular needles for knitting in the round or large flat projects, and double-pointed needles for narrow tubes. They are made from many materials - bamboo and wood give a warmer feel and a bit more grip which suits slippery yarns, while metal gives faster, smoother knitting that many prefer for textured yarns. Choice of needle material and type is often as much a matter of preference as practicality, and many knitters end up with several kinds for different projects.
