I quite like my Kaweco Sport, except for this:

Mind you, this is after I have cleaned out a bunch of the excess ink that routinely collects inside the cap.

This happens all the time. While the pen has never exploded on me or leaked outside of the cap whilst in my pocket, I have to clean out the cap and wipe off the barrel at least two or three times a week, and it is pretty annoying.

It’s a shame, too, because otherwise, I really like this pen. It holds a ton of ink, it’s nice to write with, and the size is perfect for keeping in my pocket.
