Gotta hand it to ya, you're hanging in there!
As sort of a minimalist version of your self imposed challenge, I've been doing the same thing with my little squirt. I figure if I could get by with a Case peanut and Sear's 4-way keychain screw driver, a real multitool should be duck soup. So for the past week and a half I've taken all other knives/tools out of my pockets except for my old army P-38 in my wallet. Its been there so long that I'm afraid upsetting some sort of cosmic ju-ju balance.
So far the squirt has helped fix an electrical socket, hand a shelf, adjust a door hinge, and for knife work opened all kinds of packages, cut some jute twine that tied up some coiled up 50 foot extension cord, and trimmed some flower stems of the flowers I brought home to Karen for putting up with me all these decades. The chisel ground blade makes a wicked sharp florist knife.
You've inspired me, StuntDouble!
