I agree that a lot of people coming up today get way too much into the "My folder has to be able to support a Humvee at its pivot point, otherwise it's a POS."
I do own and like many of the tacticals, but I've always looked at them as folding knives, not pry bars or hatchets. And I carry a Sebenza almost every day, but even that, I've always viewed its integral lock as a safety feature, not a device that automatically transforms it into a fixed blade.
But I also carry a Case slipjoint and an Executive SAK every day, and have been using them for most of my tasks lately. I've only recently become reacquainted with carrying the traditional patterns again after a decade of immersion in world of tactical folders. I find a timeless beauty in the slipjoint patterns, not to mention a long-term durability that seems to exceed many or most of the modern tacticals for knife-related use.
When I was growing up, lots of boys still carried some kind of slipjoint pocketknife. Sometimes we would show each other at school (1970s). And at none of those times were those knives considered as weapons. Even my typing teacher showed me his Buck Cadet; thus was I introduced to the Buck Knives brand.
So I carry my Sebenza for when I need my knife one-handed, which does happen on occasion. It doesn't weigh me down or get in the way when clipped to my pocket. But for normal cutting, out comes the stockman. It's low-key, highly efficient, and gives me a good feeling when I bring it out and use it. The stockman will fail every spine whack test known to man, even a light one

.
My worst cuts have come from closing certain larger tactical folders, esp. those with longer, heavier blades, one-handed. Got a nasty one from my SOG Pentagon Elite II, as it snaps shut lightning-fast, and the tip of my middle finger was ever-so-slightly in the blade path. Luckily, nothing permanent, but it could have been bad by the weight and speed of that blade alone. The worst slipjoint cut due to blade closure I received was once when I was closing my then-new Case canoe...again, user error. My ring finger had been carelessly resting in the blade path.
I think a lot of the "indestructible tactical" mentality is merely a reflection of the times. In the past few years, I've noticed an increase in the number of people trying to project the image of being bigger, badder, louder, tougher, outside of the world of knives. I won't point to what I think the root causes of that are, only that there seems to be a connection.
Old-timers like my dad/uncles used the heck out of their pocketknives, to make a living, almost certainly more than many (most?) modern-day knife testers. And it was really no big deal to them, and aside from getting minor cuts here and there, as will happen to pretty much any knife user at one time or other, the lack of a blade lock was never a factor for them.
