Basically instead of bringing your sledge, a crow bar, and some other shit to bang away on stuff, you could bring this and destroy shit with one tool. Most multi-tools are horse shit, this one's not so bad, a friend brought one along one time for a project I was working on and I think it was best for taking about framing and getting 2x4s out fast, or punching out drywall - that sort of stuff. I found the hammer to be the least useful part of it because while it was adequate for some stuff, there were things that you simply needed a true sledge to dislodge and it couldn't really replace that.
