This “article” is total “churnalism”, just marketing bunk with absolutely no content. Obviously I am aware what Wallpaper* is, which is mainly a conduit to help people spend their money as fast as possible like Brewster’s Millions, but this article on HN is surely misdirected.
Agreed. Most of those listings aren't even close to being classics.
For example, The Monoc Nib is very new. It didn't exist a few scant months ago. While I hope Ian Schon succeeds and it does become considered a classic, a single-piece titanium nib unit that encloses an Ultem feed is not a typical fountain pen design. (Very cool, just not classic yet... give it 20 years).
The Montblanc, and maybe the Conway Stewart may be the only classic brands there.
