I use a Moonman/Majohn A2 with De Atrementis Document Black at work daily, so you may want to take my advice with a grain of salt. That being said, I love (!) push-retractable fountain pens for any setting where you write with them at least twice a week so the ink doesn’t dry out. I believe there is close to no buyer’s remorse among those who splurged on a Pilot Vanishing Point pen, and I’ll extend that recommendation to Moonman’s really excellent knock-offs.
As for ever-ready, on-the-go ballpoint pens, a metal body Parker Jotter filled with a 1mm Schmidt easyFLOW 9000 is my conference bag staple for quick, short notes.
Among friends and family who aren’t into fountain pens, I’ve heard lots of praise for the Caran d’Ache 849 ballpoint pen, too.
Seeing that deploying airbags hit like a fist to the face and regularly break noses, maybe reframing airbags as airbombs would suffice as a deterrent.
