Favorite EDC pen or fountain pen?

It’s a great writing instrument. I just wish PILOT had thought to make the ink reservoir larger. I often use a cartridge that I refill, rather than a converter. I get about 20% more ink. But lately I’ve not been bothering with fountain pens for EDC. They’re usually terrible for signing those printed receipts.

My pen of choice is a Fisher Space Pen bullet, which is super small. Mine is abused. A little dented and the cap “data nub” came off at some point, so I use a rubber cap over it to keep my pants pockets from getting ink stains. When I’m using my portable writing pad, I’ve got a Zebra Sharbo multi-pen docked to its side. 2 ballpoints, 1 pencil. Very nicely made. This one is a limited edition.
