Did you know that a fountain pen could be sporty? This is a truly compact writing implement — Kaweco's motto is “small in the pocket, great in the hand” — that's had the same iconic octagonal design since 1935. The cap unscrews and then attaches to the back of the pen to make it full-length. This one's made of brass that will develop a beautiful patina over time. It's got a fine nib made of gold-plated steel, and it comes with a blue ink cartridge stored in the body of the pen. (You may have to tap it a few times against a hard surface to get it out, but it's there.)
