FINE-LEAD PENCILS

 
 

Functional principle and technical design:

 

In the 60´s a new manufacturing process made it possible to introduce the fine-lead pencil in different line widths.

 

The design structure of fine-lead pencils is similar to that of clutch pencils. They also feature a clamping chuck which retains the lead, but not only is the lead released but it is simultaneously advanced a short distance.
