A selection of technical pens and pencils made for technical drawing, ideal for design students, professionals and recreational sketching. Technical pens were originally designed to be used for diagrams, designs and technical drawings such as blueprints. With the rise of Computer Aided Design (CAD) technical pens now have more common uses, with some people preferring their accurate thin lines for everyday writing.
Technical pencils consist of a separate lead that can be retracted, providing a consistent lead width in contact with the paper allowing for steady lines and eliminating the need for sharpening.
Technical pens provide a thin, consistent and smudge resistant line and often the ink within will be both water resistant and permanent. In most cases they usually feature a "needle-point" nib with a metal casing, promoting the use of this pen with rules and other drawing guides.
