The Swiss tool has better polish than the leatherman tools, and very strong. But from my experience, if you not a fan of leatherman then I wouldn't bother.Perhaps a Swiss tool would impress me, but I have been very unimpressed by the design and finish of Leatherman tools compared to those on my SAK.
For me, I only have one victorinox multi tool, but with all victorinox I am happily reassured that if anything goes wrong, it will be either fixed or replaced quickly...i know that leatherman has the 25 year warranty, but the SwissTool has a forever warranty.
Compared between the two brands, the main benefit of the leatherman tools is the access speed and the pointy knife blades.
standard SAK or multi tools, both serve the same purpose....lots of useful tools in a compact design
