Their retro click pens are the nicest tactical pens I have come across. I own both a brass version (the nicest looking one in my opinion) and a zirconium version, with the zirconium version being in my shirt pocket as I type this. If they do another run of titanium versions, I will likely get one.
They need to make the retro click a regular part of their product line.
There is absolutely nothing about the retro click line that identifies it as anything other than a high quality pen.
Edited to add: Tuffwriter now has brass retro-click pens on their website. https://www.tuffwriter.com/RCBRBRUSH...ushedmatte.htm
