This is my EDC pen (and one of my lights). I'm not sure what brand it is as it is a promotional pen that my company has (it has our logo etched on the other side.) It has decent heft to it (I believe it is stainless) and takes Parker refills.
Every now and then I go back to one of my several Parker Jotters, but always end up coming back to this one. I guess I just really like how it matches my SST Maratac AAA!
I've been carrying this one for around 10 yrs now. I have 2 more new ones just like it in the event I loose this one. Except the twist mechanisms are very stiff on the new ones. I guess they will break in if and when I ever use them.
