I've used both machetes and axes a fair amount. I have a 12" Ontario machete (modified) that I love, an 18" ontario machete, and 2 gransfors axes. I also regularly process wood to start our wood stove which accounts for about half or our heat. I normally baton with the 12" Ontario. It takes a beating and never seems to care. The 18" batons well and chops fairly well when i'm actually out cutting wood (I normally use it to get limbs out of the way). That said, when i try and cross cut some FROZEN HARDWOOD in the winter, the machete just plain sucks. It has trouble digging in once you get past the bark and the vibration is horrible if you hit anywhere but in the actual sweet spot of the blade. Even then, it sometimes feels like your little finger is going to break. The axe doesn't seem to care. Even a smaller tomahawk doesn't care. The wood handle takes the vibration and doesn't rattle much. Also, the axe shape takes the impact differently. So, from my experience using both, I'd take the 12" machete as a big knife for drawcutting, batoning, clearing areas, etc. If it's winter and you plan on building much of a shelter or processing wood, even dead stuff that may be wet, an AXE is woth the weight. If it's warmer weather and no worries about havin bo build more in a frozen environment, then a machete is very versetile and a great tool that can clear areas and do things that are difficult with an axe. I'll always take the short 12" machete. However, if I were hiking or camping any place not frozen, I'd probably take the 18" machete. If I was packing my BOB bag to leave my home forever, I'd probably take both and drop one later if needed. I just know how much better that axe was with the frozen oak I was hitting on. I hope this helps a little.
