Double-Pointed Needles https://www.knitfreedom.com/glossary/double-pointed-needles/
Two knitting needle tips connected by a flexible cable. Circular needles are used for big, flat projects and knitting in the round.
Short, double-ended needles used for knitting in the round. Often referred to as DPNs.
Straight knitting needles are used to knit flat projects back-and-forth. They come in lengths from about 9-14″ (sort of like magic wands).
They are made from materials like birch, bamboo, aluminum, and exotic woods. My favorites are Signature Needles Stiletto tip, and Lantern Moon wooden needles.
