Looking at purchasing one of these knives. At first, the 4 seems like the perfect choice. Most of my folders a in the 3.5 to 4" range, and I have never found a need for more blade than that in a camping and hiking situation. Just looking for the extra strength of a fixed blade. I tend to carry a saw and hatchet in my bag for wood prep. Not really sure if the extra inch in the 5 is necessary. Any thoughts from those how own these knives would be greatly appreciated. Thanks!
