Drawing pen

More than a hundred years ago, the following article was published in the journal of the factory and handicraft industry, handicrafts and handicrafts "The Herald of Industry" (No. 4, 1884): "The well-known firm F. Sonnenen in Bonn recently put on sale a drawing pen. The drawing pen consists of one well-known shaped steel sheet that, at one end, bends around the wooden handle, and on the other it is cut with a longitudinal slot, so that it forms two halves of the drawing pen, the distance of which is equal to grams from each other is regulated by a screw with the corresponding nut.In spite of the uniform rounding which has a drawing pen in a section along its entire length, it is possible to draw straight and thin lines, since the working ends of the pen are tapered and sharp: the rounding has even a benefit in that respect , which makes it possible to type a large amount of carcass and prevents it from digging in. The shape of the pen is so simple that the inventor finds it possible to sell it for 30 pfennings. At this price it is made available for all kinds of schools, for Sunday classes of drawing, etc".

The company turned out to be far-sighted: schoolchildren of the whole planet, generation after generation, used a drawing pen (drawing pen - from a combination of German words "draw" and "pen"). For a hundred years it practically has not changed - the shape, the cog, the nut have remained the same. Indeed, it is simple - and this is perfection.

The drawing pen is widely used in topographical drawing. They draw complicated in form and small in size conventional symbols, contours of complex patterns, inscriptions, correct defects in lines drawn by other instruments. The high quality of the drawing depends, in turn, on the quality of the pen and the ability to own it.
