Item details:

With the help of the 4 pushers, the quick adjustment of the radius takes place. The fine adjustment of the radius is done as usual with the center wheel. The backlash-free mechanism with the highest precision has been specially developed for use in the professional field, for example for drawing with ink drawing instruments. The double joint enables better handling when drawing, because it is advantageous when the needle penetrates vertically into the drawing and the lead is also aligned vertically. In combination with an adapter, it is also possible to draw with an ink pen.
