Jeff Randall (the guy behind ESEE knives) has said openly (on Bladeforums, at least) that he would choose a machete over anything else (to include, in his own words, his own ESEE knives, lol) in a survival situation. I am not the guys fanboy or anything, but he has forgotten more about woodcraft than I will ever know so I will listen to him. There are tons of options for machetes. For general work and woods use, one that I have used but do not own is the Woodsmans Pal. My old man uses one, and he swears by it as do several others.
I personally at this time only own a cheapo Cold Steel Kukri, and you know, it has been a pretty good tool for me. In screwing around, I have chopped through a couple of 2x4's with it easily enough, and in actual work, I mowed down my stupid out of control rose bushes (which I inherited when I bought this place and hate).
Also, I love my parenthesis, but man did I use them a lot in this post. Word.
