Needlepoint nibs (sometimes called an “Accountant’s Point”) are definitely not for everyone! By definition they are very, very, very fine, and the trade-off is this: they aren’t so smooth. But what you lose in smoothness, you gain in precision, detail, and the ability to make a hairline-thin mark.
Although best suited for an experienced fountain pen user, needlepoint nibs are great for journaling, drawing, and small writing. I’ve heard from some mathematicians and scientists that they’re also great for notations.
This Needlepoint was done on a Bock #8 Fine Titanium nib.
