My vote is the the Leatheran Wave. I don't ever recall using it in the bush but I think it is far more useful when working around buildings, machines, or vehicles.
If I ever had to make stuff out of a boat, car, or plane I would rather have a WAVE than a SAK. Like I said, in the bush my leatherman never sees the light of day. Out at our camp property I end up using it abouy every half hour, pliers mostly, fixing wiring, plumbing, window latches, appliances etc. I've used it to get my car running again (had to direct wire my radiator fan). They're a great tool to have along for everything other than the bush IMO. When I am going to be around cars, boats, or planes I always take it along.
In the bush I prefer to have a real knife, a real folding saw, and a real mill file. Mac
