They do solve real problems. The question is whether or not they solve the problem at hand, and if they create other issues in doing so.
I was re-decking a back yard bridge with a friend and he brought a framing hammer. I'd never used one before and I always had a finishing hammer and didn't know the difference. I learned a new tool and even ran out and bought my own for the project, which worked fantastically well. It's still in my toolbox and hasn't been used since. You just don't use that thing to hang pictures on the wall because it may well f-- up the wall a bit. Using the right tool for a job is way more important than using a particular tool for any other reason.
