- In 1953, Rotring, a pen company based in Germany, began producing the first Rapidograph pen. In 1983, it added a capillary ink cartridge to the pen, increasing ease of use. Although the pen is still used today, computer-aided design programs largely replaced it in the early 1990s.
- The Rapidograph is a technical pen made with a stainless steel nib (the end of the pen that distributes ink). The pen is generally thicker in the body and extremely thin (as little as 0.1 mm) at the tip. It comes in at least 15 colors.
- The Rapidograph was the first pen to set the "standards for technical drawing that still apply today," according to Rotring.com, by improving the consistency of line weight and incorporating a waterproof pigment drawing ink.
