Needle

A needle is an item used along with thread to create armour out of either leather or dragonleather through the Crafting skill. It can be bought in crafting stores and clothing stores, such as the one in Al Kharid. They can also be bought from Moon Clan Fine Clothes on Lunar Isle and Polypore Dungeon Supplies in the Polypore Dungeon. A needle can be stored in the tool belt.

Needles can be found by searching haystacks, hay bales, or digging in the Digsite, as well as shops and tool stores. This is a reference to the idiom "needle in a haystack"

Needles are stackable items, presumably because they are small, although normal usage does not require them to be. It is suggested to have more than 1 needle as they can break, though adding the needle to the tool belt avoids this problem.

A Dwarven army axe has the same effect as a needle.

A needle is required in Recipe for Disaster/Freeing Pirate Pete where you have to get one needle (toolbelt does not count) and three reels of bronze wire for Nung.

Tricks and scams
In RuneScape Classic, needles had a highly-transparent appearance, thus it was possible to scam players by placing a stack of several-thousand needles next to a stack of 1000 or more coins to give the illusion that there were several million coins up for trade.
