Oh yeah.
I'd had small and/or cheap ones even as a child, but I bought a Mauser-badged Victorinox when I was about 18 and carried it quite a bit hiking and camping. I was thinking I lost it or sold/traded it but my mom passed away in 2013 and I found it in my dads possessions (he's passed several years earlier) with some other knives and then I recalled I'd given it to him when I was on a lull on carrying it.
A few years went by where I didn't have one and a long time friend and fellow hiker (and former 82nd ABN E5) was carrying a Swiss Champ on several of our overnight hikes here in the Western NC mountains and I was impressed with all the functions. Until then I was AWARE of the Champ in the line but always thought it was too big (even thinking it was so "overdone" with functions it was funny. ) After noticing how many tasks he did with his however I decided I needed one.
I mentioned this to my fiance (now my wife of 22 years!) and she bought it for my birthday on our first year together, and I carried it everywhere - either in the top compartment of a pack when hiking, or a "warbag" (I was carrying EDC bags before it was "cool") for everyday carry. This knife was bought with the "SOS Kit" (black leather pouch with a compass, honing stone, some safety pins, band-aids, etc.) I used to joke I could take over a small third world country with that kit...
That kit lasted from 1995 until 2006 when I lost a BUNCH of gear in an on-duty car fire (Crown Vic). The knife was burned beyond use but I still have it somewhere. I replaced it in January of 2007 but the SOS Kit was hard to find and I never replaced it. I had THAT Swiss Champ until last year at Thanksgiving when a 14 year old (but very mature) nephew admitted he's lost the one I had gotten him for Christmas the year before. I "gifted" him mine on the spot and ordered my THIRD, which is now in my "warbag" which rides with me everywhere on and off duty.
So...about 10 years seems to be the average life expectancy of a Swiss Champ for me.
A couple years ago I bought a Huntsman Plus that I actually carry in my left pants pocket... I bought two others which I gave my brother and his son-my only remaining immediate family. All three are identical with matching red fobs.
Also-I always harp to others how many functions they can do...and the BLADES are some of the LEAST used (because I usually have more primary EDC blades close at hand.) I can't tell you HOW MANY times I have used the straight pin (*I always suggest putting about a 5 degree bend in it when you buy one with the pin so it doesn't fall out*), or the ink pen (probably 50-75 times over the years in the bank drive thru alone, when I had no other pens on me or in the car). I was able to help a stranded motorist once with loose and corroded battery terminals get her car started with the pliers and file. SO many uses!
