Everyday Carry. What essentials do you carry on a daily basis?

More practical, even, at least in my experience.

Ballpoints always jam on me, requiring about a kilonewton of force and about five minutes of blank scribbling to get it going again. Then, often, they leave big blotches of their sticky ink on the page when turning a corner.

The Safari does jam on occasion, but usually, a single well-placed drop of water is enough to get it going again. That depends on the ink you use though. If you use water and inkjet printer ink, it never jams, though it is a little bloody. 30 water : 1 platinum carbon black makes a lovely grey, but it jams so bad that I need to add a bit of inkjet printer ink to keep it running. Yeah, you're definitely not supposed to water down that ink so much lol.

Same practicality but it requires more care. If you want a daily use beater, go for Pentel energels or Sharpie S-Gels for some smooth writing and deep colors.

You kinda have to be an enthusiast to make a fountain pen an edc. They require more work, are more prone to damage and has the potential to spill all that lovely ink all over your nice clothes. I just keep mine at my desk. They're a pleasure to write with given a quality make.

I don't use a Lamy (I use a Kaweco) but I can say that fountain pens are pretty nice if you like liquid and smooth writing. It's not good on other materials other than paper like hard materials but for doing math and writing it's a breeze.
