Really depends on the day, and even time of day...
9-5 Monday through Friday, normally just one. Right now it’s been a Spyderco Dragonfly, since I’ve been living in basketball shorts for the last 2 months. Normally though, it’s something in the 3-3.5” range.
After work (when I was working), or on the weekends, it’s at least two. Folder of some sort, and I’ll add in a small fixed blade. Lately the Guardian 3 has been filling that role.
Camping, hiking, or task specific, who knows. Could be any combo if folders, fixed, and MTs.
One thing I no longer carry is a small keychain knife or MT. I found they just added too much bulk to my keys, and I never used them because they were attached. If I added a small caribener, they were easier to use, but added even more bulk. The other issue was, I found myself constantly having to take them on and off to get through security areas. Airports lines, certain buildings that clients were in, and the metal detectors going into my daughter’s school... I found myself taking the knife off my keychain at least once a week. It’s one thing to pull a folder from my pocket, and stash it in the glovebox, but on and off the the keychain becomes a pain in the butt.
