I believe the right tool for the job is the tool that gets the job done. If a tool is capable of doing the job right, without damaging the tool, then it was the right tool for the job, even if it wasn't designed for that job.
I used the three knives below as prybars over several years at work. I carried the top two (separately) working on a shipping dock, where I was required to cut stuff all day long, and sometimes I had to pry open wooden packing crates. Carrying around a dedicated full-size prybar wasn't practical, I'd hate to think of even trying to carry one around all day. And trying to hunt down a prybar whenever I needed one was often a waste of time. But carrying a strong fixed-blade covered all of my cutting and prying needs in one easy to carry tool.
I also used these knives to cut thick plastic freight straps. They make cutters specific for that task, but I didn't want to have to carry one of those around all day either. My fixed-blades handled that task quite easily.
After that job I used the bottom two knives (separately) for a wide variety of uses on construction sites, including prying, and they served me well.
The picture was taken today, so you can see that they survived everything I put them through.
A good craftsman can adapt and improvise, and accomplish more with a tool than it was ever intended for.
