What are “special” nibs?
They are nibs conferring a particular effect on handwriting: the obliques (O) and the italics (0.9 1.1 …) are based on the same principle and allow a calligraphic style. In Italic nibs the thickness of the line varies by means of a differentiated shaping of the point: thin profile, broad frontal part. Thanks to that shape, the vertical lines will be thick and horizontal lines will be thin The 52 degrees offers more options than the Italic one in terms of thickness interchange ability of the line: 52 degrees is the “even” angle, the angle that the pen, on average, forms while writing. If you write with the Stipula Special 52 degrees nib and you lower the angle of the pen below 52 degrees, the thickness of the horizontal line will be affected and become broader, while vertically it will get thinner. On the other hand, if the angle that the pen forms with the paper is more than 52 degrees, the thickness of the horizontal line will be become thinner, while vertically it will get broader ni
