Best praise vs top criticism for Fisher Space Pen Bullet
“I like feeling useful. This is partially of a result of growing up in a society that often relates the value of a person, particularly men, to their ability to provide value/utility. Not a man, but I have a bit of the poison in me anyway. But by being able to feel more useful, I can feel like I have more value as a person. I really like being able to offer someone a light or loan them my knife, because it feels good to be a little helpful as well. I also have an anxiety disorder. By having objects that feel useful, I can reassure myself that things will be okay. I mean, look how prepared I am? With my 5 c's of survival, battery bank, space pen, etc - I can ritualistically organize and maintain my tools in a way that creates a sense of having acted to resolve my anxiety. It may be scary to leave the house - but look - I have all of my small objects of preparedness. In this way, my $250 benchmade knife is more of an emotional support knife than something I actually depend on to make it through the day. And I'm okay with this, and I think many of the people here are probably in the same boat as me. All of that being said, I get the most use out of my daily carry \- Fidget toys \- Pen & paper \- Zippo lighter (which is also basically a fidget toy) \- Thrunite Archer And I am excited about my new \- collapsible titanium chopsticks \- keybar”
“I do carry a pen. IMO the fisher space pen is the worst pen ever invented and writes like a dried piece of cat shit. My typical is a Parker jotter”
