Hey I know I'm kinda new around here, but you know what would be awesome? A Scrap Yard lumber dog, or a SR-77 hatchet! Something alone the lines of this thing: http://images.knifecenter.com/knifecenter/timberline/images/tm6013.jpg

Not sure about dimensions, but small enough to take back packing or hiking or even belt sheathed but as tough as all your other knives. A good hatchet with a Res-C handle, a hammer head on one side of the blade and a sharp edge on the other with a nail puller. I keep hearing about people wanting some serious chopping power and talking about these monster knives, and as cool as that idea is, it wouldn't have anywhere near the practicality of a good hatchet! The head could be a full half an inch thick, maybe more followed by a thick, 12 inch long colomn of steel clothed into a Regulator-comfort-equivalent res-C handle, with the whole thing being made out of solid hardened SR-77. This thing would put any these monster knee to shame in terms of raw chopping power, and it wouldn't weigh a billion pounds.
