I really like my Cold Steel X2 Voyager (this has the straighter edge as compared to the Vaquero Grande, which is also a good knife). After watching one of the test videos, I decided that I could try one for $60. It's a big knife with huge cutting potential, a very sharp edge from the factory, a super-strong lock, a decently comfortable Zytel handle, and a big pocket clip. It's a really nice knife for the whole $60 I paid for it.
However, I do carry my Spyderco Military more; it's slimmer, weighs next to nothing for its size. The trade-off is about two inches of blade lenght, but the S30V steel holds an edge and the G10 handles are great. The Military is more expensive, but worth it. I've also got a Chinook II, but I like my Military alot more. In fact, it was the knife I carried on my trek to the Philmont Scout Ranch.
In summary, if you're going for a little price and a big blade and carry is no concern, go for the Vaquero Grande or the X2. If you're going for a very high quality folder that will do anything you need it to and carries very nicely and slimly, get the Military. Both, again, are excellent. Be forewarned, however, that the 6-inch X2 is longer than the 4" blade length that most juridstictions have. At 3-13/16", the Military fits under this. I hope this was informative and helped. God bless you, America, and our men and women overseas.
