"There are much tougher environments to survive in than a jungle."

Very true. But instead of true tropical...I was thinking along the lines of sub-tropical. In these areas, the temps can get pretty cool.

As for the 6 inch belt knife being the only thing you need...I guess that depends on the background of the person in question. I would have some serious reservations about totally depending on one knife for all my needs when it's a fairly simple matter to have a few handy items with you.

Also....in my daily work attire (hence the spirit of this little scenerio) , a 6 inch belt knife is a little difficult for me to add...a smaller fixed blade wouldn't be too much trouble...but I've already got a load on my belt! <img src="images/graemlins/blush.gif" alt="" />
