backpacker,
I don't think you have much to worry about. For one thing, Bob Dozier is a master craftsman so you have a well-made tool by a person who has many years of experience and is admired by his peers. Second, I've never heard of any complaints about Bob's knives breaking. True, the hunter line is hollow ground but if you use common sense and don't abuse them, I think they will work hard for you. But I'm not really speaking from a lot of experience. I have 3 of his blades now and I really haven't put them to hard use. I cleaned a couple squirrels with the my General Utility (I have so many squirrels and rabbits in my back yard, I don't even have to hunt them in the woods. It's like a wild meat locker back there.
) and used it to cut the paws off. Small bones didn't phase the edge.
True, his hunting blades are not for prying but Brian Jones has used Bob's Arkansas Toothpick for prying. Right tool for the right job. As for whittling, Bob's hunting line excels. I've used my General Utility for whittling on big hardwood dowels this past winter when I was making a roof rake to rake the snow off my roof and it worked well. It was still shaving sharp when I finished too. If making snare triggers is what concerns you, you don't have a thing to worry about. That's not something that should seriously stress your Dozier knives.
I can't say how the hunting line would take to a baton. The Professional Guides Knife is probably the most robust of the line and I'm guessing that it will probably take a beating (Bob is a master at the heat treat) but I'm reluctant to do any heavy prying with it. In general, most knives aren't designed for prying. There are a few out there that excel at it. It's always a tradeoff though. Do you want a knife that will fillet a fish or dig wood out of a stump? That's why two knives are always better than one.
And three are better than two. And four are...well, you get the picture.
When I dig for wild roots I always use a screwdriver. You just have to match the tool to the job.
A nice stout screwdriver isn't glamorous but when I'm foraging, it's what I take for prying. I prefer SnapOn myself.

I get some pleasure from finding a relentlessly peaceful use for a combative looking knife.
