I have of of the new Wahl-Eversharp Skyline pens. I got it in a trade... but didn't realize that it was a broad nib. I hate broad nibs. I can't see anything on the website about nib sizes that they offer. Can you get a new nib for them? If not.. since it is friction fit.. are there recommendations of other nibs that could be a good replacement? Like a vintage Wahl nib?
