I do have a Rotring pen that I found. It's built like a tank and I love the ergonomics of it, but I usually leave it at my desk because of the weight and I don't want to be the second one to lose it. I have been using my Rotring Tikky a lot lately.
For metal body pens I've been using a few Zebra Kado. I got the first one because it looked like a standard yellow number 2 pencil. Someone was flicking the clip and broke it off, so they guy be a new yellow one and a blue one for breaking it, and I use all 3 now.
When my gf went back to college I got her a Pilot Delguard pencil. She writes pretty heavy handed and it has a mechanism to prevent breakage from pressing too hard. She really enjoys it. I don't do much physical paperwork anymore now that I'm remote, but if I wanted a pencil, is probably get one of the ones that rotates the lead as you write to keep an even line.
I feel the same way. Is leavened bread science? Nixtamalization? Collecting raw materials with interesting properties? Observing river and ocean currents? Making plant based medicine, dyes, or clothes? Tanning hides?
There are so many skills developed and improved on over time for us to have gotten to where we are. Ugg the cavemen or an early farmer or a stargazing shepard wouldn't have called themselves scientists, but they were most certainly doing science.
