The claim that Montblanc no longer makes thin-writing EF nibs is not accurate; between M, F and EF a clear difference must be recognisable. If an exchanged nib does not write like an EF, it should be complained about and exchanged again. The perceived line thickness depends additionally strongly on the paper used: smooth test pads in boutiques as well as dipping the nib into ink during test writing make the stroke appear thicker than on usual writing paper. On normal paper, the difference to nibs of other brands is mostly significantly smaller.
