The choice of nib width depends on writing pressure, handwriting size and above all on the paper used; the broader the nib, the lower the surface pressure and the softer the writing feel. Tests in the shop should therefore always be carried out with one's own frequently used paper; ideal are smooth, satinated papers with about 90 g/m², unsuitable are laid and recycled papers. With Montblanc, the nibs EF, F and M are round-ground, B and BB on the other hand straight, which leads to a clearly different writing image — this can explain why a B nib is felt to be more pleasant. Blanket recommendations are impossible; many collectors use different nib widths for different applications (e.g. EF/F for notes, M/B for letters, BB for signatures) and therefore reach for second or third fountain pens.
