I bought a Pilot Plumix a while ago as my first stub nib pen. Though initially I had a bit of fun with it, I find I don't use it much - even while I use my flex nibs quite a lot. I thought it was a little bit of money wasted, until today when i found out I could use it as a flat-head screwdriver. With reborn purpose, I think I'll be using this pen a lot more now. Has anyone else found alternative uses of/for stub nibs, or am I the sole madman here? (Embracing for hatemail. Don't worry, I do take proper care of my other pens.)
