A nib is the pointed metal tip of a pen that comes into contact with paper. It is designed to control the flow of ink, allowing for smooth writing or drawing. Nibs can vary in size and shape, affecting the line width and style produced. They are commonly found in fountain pens, dip pens, and some types of markers. In addition to writing instruments, the term "nib" can also refer to the small, pointed end of certain tools, such as a chisel or sculpting tool. In the context of fountain pens, nibs can be made from materials like stainless steel or gold, influencing their performance and feel.
