I carry these two every day

If I'm going heavier I'll also have this, an old Victorinox Officer Suisse from the 1970's, discontinued. I recently got it from a trade with my friend, it was heavily abused, having the tips on both blades snapped clean off! Why in the world would he do such a thing?

And sometimes I have these lying around on my desk for fun:
An old Colonial Knife Co. USA SAK-style Multi-tool, it is very old, rusted through, and beat up, I have retired it, it belonged to my father.
Some old Buck knices that also belonged to my father:
An old Schrade Sharp Finger that my father kept more as a collectable, as well as a funky Itallian shotgun shell slipjoint folder I purchased while at Yellowstone:

And finally, a pen that I carry because my SAK was made before they made them with ball point pens:
