I have a lovely Omas Paragon (2003 Bleu Venezia edition). The nib is a very smooth and wet medium and I have estimated the line width (with Sailor ink on normal copy paper) to be 0.8mm which is too broad for me.

I would like to swap nibs with someone for a finer grade; something less than 0.6mm.

Otherwise I'll send it off to be ground down to a fine cursive italic or a needlepoint.
