Do you know of any moves to uncap/cap a pen with one hand? I think I remember seeing something about this on Tohlz's website a long time ago, but the videos were missing.

In the unmodded pen collab Leviathan does a one handed pen uncap. Watch this video: http://www.youtube.com/watch?v=0AjtY3wlNqU

Start with taking the cap off with 2 designated fingers then work backwards from there.
