What knife would you use more in a survival situation? A small knife (under 5-6") or a big knife (over 6")? I have heard that the smaller knife is more useful to the survivalist because it is more versatile while the big knife is usually only good for chopping (ie creating shelter, firewood, etc).
If you where stuck with only one knife, what knife would it be? The small or the big? What type of knife? Or, would you go with a small knife and a dedicated chopper such as a hatchet?
Pahtoocara,
Welcome to the forum!
Everyone has to answer this question for themselves. The best way to make this decision is personal experimentation. However, since you posted the ? I'll pitch my $.02 in.
In a true survival situation, I was not well rested, hungry, and not very healthy at the moment I realized I needed to do something. I was growing very weak and needed to build shelter quickly as darkness fell and temps dropped. My first priority was shelter (fire would come later as a close second). In a weakened state every effort had to be maximized to efficiently use my remaining energy. Long story short, my big knife allowed every swing to drive deeply into the wood I needed for shelter. Precious energy must be conserved when don't have much left. My big knife makes shelter easier on me. It makes fire easier, whether its making a fire or building my pyre. That could translate into making water and food easier by having the fire purify/cook it. So, I depend on my big knife. There is a fine line of too big, that is purely personal preference, dictated by many things such environment.
Now, while I agree a big knife can do most everything a small knife can do, but efficiency/energy influences the decision again. My big knife can do many small tasks, but I may expend large amounts of energy doing so. A small knife has its place in the intricate detail work so often needed around camp. It is light and comfortable for long hours of carving/wittling chores.
I carry a two knife set (pic links below). They are both in the same sheath and always with me. Whatever the circumstance, I have a head start in putting the odds in my favor.

My decision is based personal survival experience. Simulate a true survival circumstance, as best you can, and what you need may over-shadow what you want. Some people do not function well having gone without food (some sugar thing, I think). While others, are hardly aware of the inconvenience. Under a controlled environment simulate no food, possiblity of injury, frustration, anger,etc. Then practice what you must do to deal with it. My big knife - wouldn't leave home without it.
Hope this helps!
