I keep a space pen in my pocket at all times. A Field Notebook in my back pocket, and I'm always ready to write things down.

Same, I've had one of these pens since 2007 or 2008. First saw them in HS, when the $20 or $30 sounded like a lot of money, when a grandchild of one of the founder(he claimed, and it would be an odd claim to make if it weren't true) was in a class of mine. I used to get made fun of, which hasn't bothered me since high school, until people started realizing they were always asking to borrow it to write down a note or sign a receipt.

After watching a YouTube of Adam Savage proclaiming the joys of the space pen, I went out and bought one of my own.

Great decision.

I watched the same video, love Adam and Tested.com, my favorite aspect of the pen is how small it is when you put the cap on. Fits in my pocket and I can't tell its there.

Edit: http://www.youtube.com/watch?v=bypi7h6WOGg This is the video of stuff Adam Savage carries on a daily basis. Interesting if you are a gadget nut.

I took it another step: http://imgur.com/JvMbVe4

I found a Stanley screwdriver that is great to carry around in my pocket. I used a bit of Instamorph to build a clip for both and now they don't slide around in my pocket!

I love this stuff.
