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.
Great decision.
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 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.
