Like others, I have a number of knives, folders and fixed blades. I bought the larger (10") blades with the PNW cascade range in mind. While their main attribute is size, they stay in the truck because of that size. They are much more capable in some tasks, but if you won't keep them hanging from your belt while hiking, they are at best a camp knife and not a survival knife.

Large format SAK's (Rucksack/Trekker), locking folders and smaller fixed blades are what I carry on my belt/pocket. A Leatherman MT is in my backpack.
