Back when I constantly needed a pen I used to use a Parker espirit telescopic fountain pen, since it was the best small fountain pen that cost little enough that I wouldn't mind loosing, but it was still small enough and good enough for my tastes. More recently since I stopped needing an actual pen with any sort of frequency it just kept getting dry and I just decided to stop carrying one.

This days the only thing that I physically write with any sort of frequency are ttrpg character sheets and for those I just need a good pencil, so I moved to the wsd magnetic 2.0 mm lead holder. I just love it both as a great mechanical pencil and a fidget toy

I've been using 0.7 point Pentel Supremes since I began high school

I carry a Fisher Space Pen everywhere, but I switched its cartridge for Pilot Hi-Tec-C refills. It takes a little fiddling to get the refill in there, but once it's in it works great!

I commented this elsewhere, but I figured it deserves it's own top level comment.

You can take an affordable stainless steel zebra f701 and swap out the ink with a fisher space pen refill for a solid, utilitarian pen for less than 15 bucks.
