A little story about pens and pencils.
How often do you use office supplies?
The most distant ancestor of a pencil and pen was a firebrand from a fire - this was used to draw rock carvings
The famous goose quill. Usually, when preparing for writing, the pen was cleaned in hot sand, cut and sharpened
The first description of a graphite pencil is found in a treatise on minerals, written in 1565.
Put the rods of black stone (graphite) in a wooden shell proposed by the French chemist Nicolas Conte in the XVIII century - it allowed you to save, in fact, graphite. In addition, it turned out that a pencil made using this method even wrote better
The first ballpoint pen. In fact, it was invented for the needs of military aviation (at the height of such a handle ink did not leak), but soon the producers realized that this was a real revolution. When in 1945, the first batch of ballpoint pens went on sale in New York, the authorities had to display a cordon of several hundred police officers - there were such lines. For a day I managed to sell 10 thousand pens, although it cost a novelty not cheap - so much was received by an American industrial worker in 8 hours.
Eraser. First, to erase what was written, bread crumb was used.
The first marker in the history of mankind was invented in ancient Egypt. This writing device was found in the tomb of Tutankhamun: a copper handle with a leaded pointed tube inserted into it; Inside the tube was a reed filled with ink that seeped through the fibers of the stem, accumulated at the pointed end and when writing left a clear mark on the papyrus.
