Hey, Rodion, welcome.

I have come to respect the Leatherman line, and own quite a few. The Wave II is my favourite of the bunch; I own several, and carry one all the time.

But - trying to think outside the box - is a standard multitool what you need?

The SAK you already have is a good cutting tool, and in addition can handle small pliers-related tasks. I own several of this type, and I can assert that they hold their own in realistic wilderness situations. The SAK saw is particularly excellent.

So, what tasks do you want to achieve with a multitool?

In a BOB that you don't have to carry on your person, you may get more utility from a large vise-grip with wire cutters (7-10")), a crescent wrench, a heavy-duty flat screwdriver, and a strong multi-bit screwdriver. Multi-tools are great, but real tools accomplish more for much less expense -- assuming you can afford the additional weight and bulk.

Just a thought.
