My grandfather used to use something similar to this when he was working in the shop on the farm. Not as fancy mind you. From Grand Illusions
In the Medieval period, artists and scribes often used a metal stylus in order to draw on a specially prepared paper surface. Generally known as Metalpoint, or Silverpoint when the stylus was made of silver, artists such as Leonardo da Vinci, Dürer and Rembrandt all used this technique. www.silverpointweb.com gives a lot of information about how it works.
The pens we sell are a modern version (and do not use silver). The solid metal ‘nib’ consists of a metal alloy, that leaves a mark on most types of paper. If you use the sort of paper typically used in printers and photocopiers, the pen leaves a mark that looks as if it was made by a pencil. However the line will not smudge, and cannot be rubbed out.
Just the kind of thing I’d love to have handy in my Tom Bihn bag, but darn, I didn’t ask for one for Christmas. I think this would make a lovely New Year present though 🙂
