I guess I am the odd-ball here.
I think that chopping and batoning are reasonable expectations for a knife unless the baton is a sledge hammer.
I am sure that a FBM would be ok as a prybar, shovel, and screwdriver. I wouldn't want to do those things with my FBM unless it was an emergency and I had no other tools or improvised solutions. I would much rather have the right tool for the right job than to take the chance of possibly damaging my fine cutting instrument.
How sharp will that razor sharp knife be after being used as a shover to dig dirt, sand, pebbles, and rocks? How much time would it take to bring the edge back to its original glory? Why would I want to dig with my stupid sharp FBM when I can pack a little plastic/composite shovel that weights nearly nothing. You can also easily improvise by sharpening a stick to dig with.
Prying is probably ok with a thick tip knife like the FBM depending on what is being pry ed apart. But again...why? A crowbar is much cheaper and does much better job without the razor sharp edge possibly cutting the hell out of me if I happen to slip when I am really leaning into the pry.
Screwdriver??? Hell No! Not with my knife at least. The possibility of ruining the tip or edge is just too high for that sort of task. There are folks that can use their knives as screwdrivers and can probably get away with it. I for one will not take that chance.
I view my knives as fine cutting instruments because a knife it is designed to cut (small knife) and chop (big knife). They should excel in that capacity. Whether or not they can be used as makeshift crowbars, shovels, screwdrivers, etc.... really is of little importance to me. The ability to do those things are obviously nice to have if I can get them without sacrificing cutting/chopping performance.
I am not saying that others are wrong. These are just my personal opinions. If others are comfortable with using their knives as prybars, shovels, and screwdrivers then who am I to disagree. Your knife...do what you want with it.
