I know this is the 4" knife thread, but in fixed blades, I like them bigger if I am going way down into the swamp. A big knife can do more. The 4" blades are handy for light work and carry well on a hike or something, but the big knives can do it all, as has been shown. Dan used a Scrapper 6 on a deer hunt. That's a good all-around size knife for the bush.
