Wonderfull Maximum minimalism!
I got my first P-38 curtesy of Uncle Sam when I was a young guy not longest of high school and enlisted in the U.S. Army. It didn't take long to discover how useful it was as a can opener, as well as a scraper, screw driver, small pry took for those jobs a thumb nail is just not enough. Its also a scribe, for scratching a cut line on 2x4's. An old semi rusty Speaker U.S. is still in my wallet. They make a P-51 that is even better.
For a long time, I carried two and three layer SAK's, but later in life I went back to the Sear's $=way keychain screw driver and P-38 in the zip compartment of my wallet. That eliminated one whole layer of SAK. Like the 58mm classic being able to deal with 98% of pocket knife jobs, the keychain screw driver/P-38 can deal with 98% of the loose screw jobs in daily life. With a SAK classic on the keyring and a P-38 in the wallet, you're pretty set for the unexpected little emergencies of life. Add a Sear's keychain screw driver or the Victorinox quatro, and you've got all the driving and opening capability a 84mm or larger SAK without the lump in the pocket. This leaves more room for a dedicated cutter if you need, like an Opinel or Victorinox florist knife with that wonderful chisel ground blade.
