I've tried to make a knife that can do everything, and I learned that you can make something that gets a C+ grade in every task and that's if you want to keep it well rounded to perform every type of task. If you want to get an A+ grade in one area you're going to have to sacrifice another attribute down to an F or D-.
So you can either settle for a C+ in every attribute, which will be some form of sharpened pry bar object, that you can chop a tree down with, do a semi decent job at feathersticking, prepare your food in a somewhat uniform manner, baton and split wood quite well, and make a decent go at clearing branches and making notches in wood. It will do everything to a passing level of acceptance.
But it's not going to win you sushi chef of the month presentation awards, it's not going to give you the cleanest shave, it's not going to be as good as a real axe at felling a tree, it's not going to win over the bushcrafting community and replace their fav puuko scandi knife.
So basically you can have a jack of all trades that performs sub par at everything, or you can make a highly specialized knife that scores an A+ in one particular task. The jack of all trade type knives will probably be used as survival tools and given to soldiers, where you don't need something that wins awards you just need something that can do everything to a shitty standard and keep you alive and not weighed down with 20 different knives.
So your specialist groups are still going to buy their specialist knives designed for their exact task, the sushi chef is still going to use his single bevel ultra fine knife designed for his trade. The wood worker is still going to use his marking knife (Think kiridashi)
And crocodile dundee is still going to use his ass kicking knife.
