"EDC" means it's a tool used every day, and that's 18/7, unless you happen to sleep with a knife clipped to your boxers. That makes it a personal carry knife, not necessarily a large work tool. Since you can carry a 4" folder for that work more easily than a 2" fixed blade, it's preferred. And a look around at work, on the street, on duty, in the FOB, that's mostly what you see.
Some go more for a multitool, but the 3.5" folder with locking blade is 99% of the commercial knife market new models over the last 25 years. That's about as far as it can go with any consistency, tho. From there, it's buffet of choices in either extreme.
Since my focus has been on durable duty knives - which some mistakenly call tactical - I've narrowed down features to a short list of what will give good service. Again, it's a personal knife, and any expedient use as a weapon should be considered as minimal. A drop point flat ground blade with nitrided finish, liner lock, G10 scales will do it.
The drop point is the most useful shape, and offers a lot of versatility in various cuts. Flat ground from edge to top cuts with the least friction, and is easy to clean. The nitrided finish is extremely scratch resistant and creates another step up in a friction free cut. The liner lock is the simplest architecture, thin for carry, and in this price range, done right, unlike cheaper knives, even from big brands like Buck. The G10 scales aren't inexpensive and require more labor to shape, but are nearly indestructible, stiff, won't collapse against the blade, and offer grip. In my experience, I've never dropped a G10 handled knife, but expect a metal handled one, aluminum or titanium, to hit the concrete. That isn't user friendly when it slithers away when you need it most.
There's a lot of emo whiz-bang in the knife world, and the marketing does everything to exploit it. Concentrate on the features you need, and you make a better choice. You're better off with a lockblade SAK than a bayonet, keep in mind, it's an everyday personal use knife, not that specialty tool in the belt bag or chest plate rig for combat.
