There are allot of super experienced woodsman chiming in here which is really outstanding as it allow the rest of to benefit from there experience. Ricks jokes about his "laziness" which might be better defined as efficiency which is born from seasoned experience not from lack of motivation the attention he gives to his craftsmanship of wilderness tools is a testimony to that. Also his large blades are sharper than most peoples carving knives..
Seriously though, I;ve experimented with this very subject over the past year by attempting to purge the middle man from my tool set up, and only using a larger blade and a folder..
on my average camping trip the blade based tasks usually involve processing dead fall oak for fire wood, and shelter poles, and other plants for bedding when needed
prepping various stages of tinder and kindling, food prep, and various cord cutting, (however most of the cordage i use has is pre-cut into selected lengths in my shelter kit, use less 550 that way) most of those types of tasks are easily done with a lager blades. including feather sticks and such. Here are some pics from various outings where I used a larer blade for most things
making sparkable tinder:
making traps
splitting hardwood
however as many know allot of the more common tasks can be done with any knife regardless of size
for most applications i use a smaller blade, simply because it attracts less attention , is widely more accepted among people encountered while in the woods, and truthfully I feel less like a rambo style survivalist that way. also having a sharp blade that is lively in the hand at quick access is extremely handy for finer tasks and utility cutting when you don;t want a large blade on your belt, or when your fingers are to cold to muck about with a folder
that being said there is always a larger blade in my bag because when the chips are down, carving a trap, cleaning a trout or making a net needle (while awesome, impressive skills and worth while skills) are not going to keep me dry or warm... that will depend on my ability to break down wood in to dry components for fire or stripping vegetation for covering or bedding for a shelter.
Now also the odds of me being in a situation like that (other than ones I have deliberately put myself in to test myself) are not only unlikely but almost impossible.. but hey we all like to pretend, that's why we're here. anyway I digress
I'll go with my original answer it takes more skill to learn how to use a large knife to do small things, but requires more energy and time to make a small knife do large things..
