I edc my leatherman surge, which is just a Wave on steroids. I love it, and it seems to be totally indestructible. I have no experience with the swisstool, but i can simply say that I love leathermans. The blade steel isnt incredible, but leatherman seems to do a good heat treat on it or something because it performs about as well as my 154cm blades. As for the saw blade, if the one on the wave is anything like the one on the surge, i find it to be very effective.

just my 2c, i would go with the leatherman
