I've carried Leathermanbrand tool(s) all over the world for decades. Having worked in places where tools were either shipped in/Carried in personally, I've found the Leatherman tools an essential fallback when in places where tools were suddenly and deliberately stolen ("You have so much and we have nothing...") and had to assemble entire factory robotic systems with almost no tools plus my Leatherman for the fine work, which was
NOT stolen, simply because it was on my belt and at 6'5" I was the largest man in the entire country. Gerber or Victorinox SwissTool are also prefered by some people YMMV.
Off brands have never held-up for me, but the Leatherman tools have taken professional level abuse for decades. The only down side with multi-tools generally is that even when they are fine tools, their blade steel has generally been poor, but then again, I am a knife snob, so I generally carry a pocket folder of some kind, in addition to the Leatherman. The quick access folding knife (currently a CQC-11, and in the past my CQC-7) served for mostly peace of mind, should I ever have to hoof it out of the country, and for work like opening boxes, lite dinning tasks and on a very few occasions, for self defence. Most parts of Asia I was in. they understand knives, even smallish folding ones, and backed off quickly upon presentation.

Ps. If I hand to use a Leatherman Tool for self defence, the needle knose pliers would give a TERRIBLE TITTY-TWISTER !!!
