Baby’s Bottom Nib

Baby’s bottom nibs seem to us to be a term that has lost all sense of its original definition. Without meaning any offense to new pen collectors, they are the ones who tend to use this term quite liberally for any number of writing characteristics. Nib expert extraordinaire Richard Binder defines a Baby’s Bottom Nib as “A condition in which the edges of the nib slit are too rounded where the slit meets the surface of the writing pad, so named for the resemblance of the nib’s tip to the profile of a baby’s posterior. A nib with baby’s bottom will usually be remarkably smooth, but capillary action will hold the ink too far away from the paper instead of drawing it toward the paper as intended, and the nib will have trouble starting.” https://www.richardspens.com/ref/gloss/B.htm
