I own a Satu...it is a big monster of knife...10" when opened. It's not the most pocket friendly knife and I seldom carry it because of it's size. The Dua is a more reasonable knife for EDC.
So . . . what you're saying is, it's almost big enough for my liking? Yeah, too big for my tiny hands, but I feel better about myself when my knife blade over 5 inches long.
