I’m always looking for the smallest linewidth and the hit-tec-c .25 has been my favourite so far. The Jetstream is new to me as is the Kleid notebook - looking foward to trying them out!
How about you? Any favourite super fine lined writing instruments you like to use?
I have some 0.18 mm rOtring Micronorm technical pens. Absolutely satisfying to use.
The Isograph comes in sizes down to 0.1 mm. I’ve never used one of those.
