On my keyring I have a 58mm. I often change depending on mood or car I'm driving. I made a green custom manager with Spyderco blade when I got my green X6. Then I made a copper rambler for my brother and (of course) had to make one for myself. Then I decided stealth was cool, so my black car key got a black midnite manager friend along with a tiny flashlight…realizing that I had two light sources, I went to a black manager. (I can't describe what's going on in my brain - 😀).
On my belt I have a Companion that went from red to black scales (stealth again), but recently I swapped the front scale to one from the Marlboro topo knife as I like that look.
In my car I have my custom "Streetfood" model: Serrated main blade, combo tool and (Adler) fork, a rescue tool in the center console and a small EDC pouch with a Cyber Compact (with magnet in the driver) for the extra 4mm bits along with Knipex pliers, a 711 mini ratchet and Steinwhale stubby bits.
In my travel kit I have a cheese knife and a wine master so that I don't have to use dull AirBnB knives.
