The thing with multi-purpose tools is that there is often a compromise. It will seldom do all its functions as well as a device that is designed to do a particular function exclusively. That said, it is better to have a hatchet that is also a mediocre hammer than to have nothing but a stick to drive a stake. If you are happy with the compromises, and are comfortable using a tool, then go for it. If you think it's a gimmick... don't get it.
