+1 Tom.
All of the hunting knives I usually carry are fairly small.
If I am going into the deep greenery I might take an axe, saw, machete or combination of those with me if I intend to stay a while.

I find the "Survival" knives pretty much useless. They are not really big enough for serious chopping and are too big for most other chores. I have also noticed that if they have serrations on the blade they are near the choil, exactly where I don't want them.
