Recently I did a wire cutting test with the several multi-tools I have on hand. All were able to cut solid wire well enough, but results varied on braided wire.
On braided steel picture hanging wire, the most consistent clean cut was with a Swiss Tech Micro Tech 8 in 1 and a Leatherman Core, using the notch below the plier head. While not 100% clean every time, the better performers did well most of the time. They were, in descending order, Swisstool (original), Super Tool 200, Spirit, Squirt P4, PST, Juice CS4 and Swisschamp.
All of them, actually, will do the job, if needed. I can and have been in situations where what I had on me was my only option. Years back, I had to frame and hang a gallery exhibition (I'm a photographer) with my Swisschamp, and six weeks ago did the same with a Core. In the main, I prefer dedicated tools to any multi-tool, but sometimes, rather than go elsewhere to retrieve the proper tool, I find it easier to reach into my pocket.
There is no real significance to these test results because some of the multi tools had been used more or less than others, so it wasn't really scientific, just demonstrated differences in my particular collection. The main thing I learned from all this is that I have too much time on my hands.
