Recently picked up the Silky Nata 240 Outback Edition to be a one tool replacement for the Fiskars hatchet & the Ka-bar Jarosz Choppa in my packable trail maintenance kit (which also includes a Silky Bigboy saw).
Haven't had much chance to use it outside of delimbing a large fir that fell across a local trail but my impression is that it feels & swings like a cross between a European/Western-style hatchet & a big knife/short machete. In my hands, it chops almost (but not quite) as well as a European-style hatchet because of the blade's negative angle relative to the handle and its forward-heavy balance, and it clears brush just as well as a big knife/short machete because of its blade length (though its greater mass means I can't swing it for as long before fatigue sets in). So it's sort of a "jack of all trades, master of none" in the way all multitools are.
That said, I think some of that impression may be from my lack of experience in the use of a traditional Japanese hatchet like the Nata, and I am sure that it will become an effective single tool replacement for a European/Western hatchet and a big knife/short machete for my purposes as I become more familiar with its characteristics.
