You can't go wrong with a Case Copperhead if you like that size. It is probably my favorite pattern in that size range.
I did a "challenge" a few years back with a friend on the forum here and just carried a Case Small Texas Jack, Amber Bone CV, as my only pocket knife (well, along with a Victorinox Alox Cadet but that was non-negotiable - that is a true EDC-for-life knife).
At first it felt a little odd not having a rotation but after a while it just seemed normal and right to have "my pocket knife" (singular) on me. I permanently bonded with that knife and it is still one of my go-to knives and is always on my desk.
It was originally a 3-month challenge, but when the 3 months was up, I felt no particular need to change it up and it ended up being about 6 months before I carried something different.
There is something to be said for finding a pocket knife that becomes your true friend and companion. The family backstory makes it even better.
Fun to read about your journey with your new knife.
