Been a knife snob for quite a while and still revert back to Buck 112 light more often than not.
The plastic iterations of the 112, like the 112LT, 422 and the basic Slim
are handy.
My son still likes the old red handled Boy Scout model I bought him as a teen, and I happened across a Like new black handled 422 a while back in a cutlery store. It was in a large bowl of loose folders at the front counter, most of which were the result of misc finds at estate sales. The black 422 didn't have its nylon belt sheath, but it appeared brand new. if it had ever been used to cut anything, you couldn't tell by the pristine blade surfaces and the the factory edge. The plastic handle was unmarked, as well.
Naturally, it's not nearly as slim in the hand as the slim, which makes for a chunky outline in a front pocket, but it has a better feel in the hand because of its similar width to the standard 112.
I'm a bit conflicted on the Slim variations. I have Slim versions with both nail nick and thumb stud, and 420HC and S30V, with plastic and Micarta scales. The slim profile with a pocket clip is handy, granted, but the Anniversary 112 and the Finger Groove 112 are very comfortable and reassuring in the hand.
There aren't many reasobale EDC cutting tasks that can't be tackled with the diminutive 3" clip point. The upgraded S30V steel and the slightly thicker handle aren't a bad compromise, though.
Probably why I have so many Buck 112 variations and Spyderco Delicas, comes to that.
