I have a no-lead brass pen. It isn’t as heavily knurled as this one but it has something this pen doesn’t have: cap threads on the tail. So when you take the cap off you not only have somewhere to put it, but the pen gets better balanced.
Plus, Fisher Space Pen refills? Really? Very limiting. Mine takes dozens of gel and roller refills in a rainbow of colors and line thicknesses and ink types. I have a Space Pen. Not fond of how it writes. If I’m ever in space I’ll use a pencil.
