Tactical weapons are not the best camp tools. The hatchet is the best camp tool IMO because it is good at chopping and splitting. Tomahawks can do most of what a hatchet does but they are less efficient at splitting wood larger than wrist size. It can still be done, you will just have to beat the head through or use wedges. I think for light camp duty, a hawk will do fine if you want the cool factor. I would stay away from the pure fighting hawks with thin blades and no eye for camping.
I have a Fiskars hatchet. It's a really good tool, but eventually the plastic will wear out around the head. By then, you'll probably want another hatchet anyway. The Graintex single bit camp axe got an excellent review on Wood Trekker and the Husqvarna hatchet also has great word of mouth. Cold steel tomahawks are a good place to start. If you get the spike types, you will not be able to baton them through logs. Keep in mind these inexpensive tools will require a little sharpening on your part. Happy chopping!
