It does not really help my handwriting, but writing with a fountain pen is much more pleasant. I also like the objects, the ink bottles and the small refilling ritual every now and then. But yeah, my writing is still terrible.
I don't know what that is and googling gets me nothing. I'm also unclear how saying "you don't need a £200 fountain pen to write well" offended you. Have a great day anyway.
My argument is simply that it's significantly easier to learn to have good handwriting with the right tool than with the wrong tool.
Surely there are also people with excellent handwriting even writing with sub-optimal tooling.
