I have zero affiliation with these guys, I just like their product. Machine Era is coming out with an updated version of their 'original brass' pen, offering it with a pocket clip. Brass, stainless steel, and DLC stainless. Comes with the Schmidt fineliner refill & a Pilot G2 gel. Get in on the Kickstarter here - https://www.kickstarter.com/projects...ine-era-markup

In the comments section they said they may (most likely) will also offer a copper version. I'm in for a brass one, and will get a copper too if it's offered.

Here's my original brass pen. Currently using it with a Pilot V5 rollerball cartridge. GREAT PEN. Good shape, good weight, and ZERO tip wiggle.
