Beautiful pen, but $140?!? How much work actually goes into one of these? Run a piece of Ti on a lathe, touch it with a torch to get some cool colors, drop in a parts kit and a Fisher space ink refill, and put it in a box. Someone ping me if these go for around $50.
Are you skilled at making pens like this?? I certainly can't do what Matthew Martin does (harder than it looks in my opinion). But if you can build pens as nice for $50, I'm in for a half dozen!
