I wonder why it’s called that? Anyway, if Gerry Berg says it, it must be true. Not that I know the man personally, but he seems quite the Sheaffer authority.
The pen came in a box from TAO, who likes to put surprises in boxes. WASP means “W.A.Sheaffer Pen,” and I see that a gazillion decades later we in the branding community still heart our acronyms.
No one associates flex nibs with Sheaffer, but this one has a soft, flexible WASP #2 nib. After a smoothing job with Micromesh, the nib is quite the show-off. I’m glad it is. Otherwise it would be the equivalent of a handsome man with no aptitude for conversation.
(Note from 2014: David Isaacson (Vacumania) discovered this material was called Lahn around 2008, on the back of an ad for another Sheaffer! Adding this note for Googlebots to find.)
