This is a PSI Anvil pen in aluminum. The blank is called Rocket Red, and is from Bear Tooth Woods. Since it's a relatively small diameter, and is aluminum, it's very light. I like it a lot more than I thought I would!
You have to move the clip out of the way for assembly, but a hex key is included with the bushings. Classy. This is my first time using the Schmidt mini click mechanism. Amazing little piece of technology.
