I’ve been asked before about what nibs are able to be swapped in the Noodler’s pens. Nathan Tardif shows in his video how to change out the nibs of a Noodler’s Piston Fill pen. He gives a demo of this while making you drool over a host of vintage Waterman, Sheaffer, and Conklin flex nibs. I’m sure for a lot of you this video may raise more questions than answers, but it’s interesting to watch nonetheless.
