My oldest 110 is something close to 20 yr - and fine. My EDC for eons - and over 30 now - is a larger SAK. It was always in my pocket. I sent it back when the scales would no longer fit - the scissors were replaced, too - as were the tweezers and toothpick - gratis! Sadly, the only way the blade would cut butter was if heated. That was perhaps due to my 'attempts' at sharpening it. While you can shave - or pare fingernails into layers - with my wood chisels, I never 'mastered' sharpening the double edge with my collection of stones. That changed last summer when I bought a Spydie 'Sharpmaker'.
I have a Buck 279 Folding Alpha Hunter that 'should' last a long time... it has a nice bushing to rotate the blade on - not bad for $34 from Wally World. Of course, as a liner lock, that may be more of a life ender - except for Buck's waranty. The lockback 110 is still a hard act to follow. Oddly, my secondary 'carry' for nearing 20 yr has been a 301 Stockman - finally sharp again as well - and still 'tight'. I've never owned a Case...
