I offer a Nib tuning service for new and older nibs.
Having the tines aligned and the tip hand polished and smooth often gives a bit improvement in the smoothness and writing feel of any nib.
Even a cheap nib can be brought up to a standard equivalent to far more expensive nibs.
Each nib takes between 30 to 90 minutes to hand align and tune (depending on its starting condition).
Steel, Titanium, and gold Nibs can benefit from this process.
Prices start from around £40 / $60 to have your nib custom tuned.
