A writing implement or writing instrument is an object used to produce writing. Writing consists of different figures, lines, and or forms. Most of these items can be also used for other functions such as painting, drawing and technical drawing, but writing instruments generally have the ordinary requirement to create a smooth, controllable line.
Another writing implement employed by a smaller population is the stylus used in conjunction with the slate for punching out the dots in Braille.
A writing material, also called a writing medium, is a surface that can be written on with suitable instruments, or used for symbolic or representational drawings. Building materials on which writings or drawings are produced are not included. The gross characterization of writing materials is by the material constituting the writing surface (for example, paper) and the number, size, usage, and storage configuration of multiple surfaces (for example, paper sheets) into a single object.
