I'm 32, so I'm probably what you consider the "younger generation".
I went through a large portion of the full gamut of "tacitcal" folders. Spyderco Military, Benchmade 710, Microtech SOCOM and LCC, etc. I even carried a Severtech for quite some time. And although I didn't own them, I've handled many large folders through passarounds. Like Spydercos Police 3 and Barong, ZTs 300 and 550, Kershaws Tilt and Spec Bump, and others. And of course, the Sebenza.
What kinfe/knives do I use most these days? A 2-4 bladed slipjoint, like a stockman, mini wharncliffe trapper, or a congress. I hardly ever carry a modern "tactical" knife...at least with the intention of using it for utility (I carry a SE Endura Wave...but that has a different purpose). I found that I really don't have a need for a big, heavy knife with a thick blade and a robust lock. It has been a year or so that I've been carrying a slipjoint as my primary EDC, and I've yet to come across a situation or task that made me wish I hadn't sold my 710 or Severtech. I simply don't have a use for such a knife, so I fill my pockets with something else.
What do I cut with my slipjoints? The same thing I cut with my bigass tactical folders. Looking back, the word "overkill" seems an appropriate description. Overkill for me, anyway. I'm sure others benefit from having a larger, more robust knife, but for myself, living in the city, I prefer a smaller, more controllable knife with a thinner blade that slices well.
As for blade shapes, that's one of the main reasons I like traditionals. With a 2-4 blade knife, I can get at least one straight and one curved blade. Between them, there's little I can't cut with ease and precision. I never liked tanto blades, nor am I a particular fan of folding prybar type blades that are so thick they can't slice cardboard without getting stuck. Again, I'm sure others can benefit from them, but I can't.
I don't know if my answers will be the ones you're looking for, but I'd like to offer my perspective, having come "full circle", as it were, having started with traditional knives like the SAK or stockman, then "graduated" to expensive "tactical" folders, and then back to the traditional knives of the older generations.
Looking for a GEC Bull Nose sodbuster in Nifebrite acrylic. If you have one to sell or know where I can find one, let me know.
