Needle

Needle is a tool used in various fields such as medicine, sewing, and tattooing. It is a long, slender piece with a pointed tip at one end and a hole or eye at the other. The earliest needles were made of bone or wood; modern ones are manufactured from high-carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance.
