Keychain or smaller knives with a pen

[EZ Bake]

So I've decided to retire my old Victorinox Midnight Mini-Champ. It's pretty beat up and I've been looking for something else to go on the keychain for a while anyway. I've tried carrying a Leatherman Style PS, but it lacks a pen. I enjoy having the tweezers back since I stopped carrying a larger SAK a while back, but the pen seems more important to me. I bought the Midnight Mini-Champ back before I started carrying a good flashlight, so a knife/multi-tool with a built-in light is definitely not necessary anymore. I keep thinking about the standard Mini-Champ, but I wanted to make sure of what else is out there first.

This got me to thinking about carrying a Fisher Space Bullet-pen, but I'd really like to carry less in my pocket rather than more. What models of any knife (aside from the Vic Manager/Mini-Champ series) have pens in them?

I don't really care if it's removable or slide-out, but I'd like it to be small and/or slim/lightweight. The explorer is getting a little large in my opinion, but I'm sure there are smaller knives/multi-tools out there with pens in them.

I have a swiss card, it fits in my wallet and has the pen in it. An alternative would be a pico pen:

I'd considered the Swiss Card, but I'll be honest man - that Pico Pen looks pretty stinking cool!
