I have 6 Leathermans in total, and 7/8 SAKs and 2 Swiss Tools.
I hold them all in high regard.
Unfortunately Leatherman dont build their tools as good or use as high quality materials as Victorinox.
I replaced a Swiss Champ with a Leatherman Wave for work. I get 7 years out of the Champ before it wears out, I get 2 from the Wave. Ive worn out 2 champs and 1 Wave. Same job the SAK lasts longer.
They are both good tools!
