Glock field knife. For the money I think they are a great survival knife. I really like having the ability to hang it from a web harness, and it can be hung upside down. Also it can be used on either side as well, as the latch is just centered on the front.
The only thing I would change is harden the steel a smidge.(its not that bad though) Well ok I might add another feature, which the user can do at home, but add a stud on the pommel. Should you ever ever need to use it for bashing then you could.

Never have been a fan of Ka-bar.

Let me save you some money. If you can find a better knife for $22 than the Cold Steel Lite Pendleton Hunter, please tell me what it may be. I bought one to give as a Christmas gift, then bought another for myself. I have another knife for my belt, but the Pendleton Lite Hunter is in my daypack as a back-up and I'm very pleased with the purchase.

the puma hunter series are great knives i have a puma leather hunter and it is awesome. but if you make knives I would make one out of a leaf spring. I have one a black smith made for me that is undestructible.

The plain old Buck Special works pretty well. Mr palumbo, I love that little Cold Steel knife. I gave them away as Christmas gifts a year ago and I always have one in my pack as well.

I would go with a Cold Steel bushman. simple knife and holds and edge, and I would say I've put it through its paces here in PNG.
@ AJMcClure: What are you referring to when you say a Tramotina cane knife? Here in Papua Niugini everyone has with them what is called a bush knife, or busnaip in Tok Pisin, that is made by Tramontina out of Brazil. They range from about half a meter to about a meter in length. I love the knives, and am wondering if what you are talking about is the same thing.

you can find the bark river gunny or bravo 1 for around $150.

A classic K-bar.

In pig country I carry a Cold Steel Boar Hunter with 8.75 inch blade for stabbing and a Cold Steel Mini Tac Skinner for gutting. The Boar Hunter's straight cutting edge does not make it the best for gutting / skinning. However, it is long enough to hack through light undergrowth.

When hiking during the off season, I carry the Cold Steel Bushman. My walking stick is a hardware store pushbroom handle. The pushbroom handle's tapered end fits very well into the Bushman to easily make a spear.

My hunting buddy carries the Bushman and keeps it razor sharp. I saw him gut a pig and two deer with it this season. Last season I saw him kill two armadillos and an opossum with it.

dont get the bear grylls knife, youll regret it. Get the Cold Steel Bushman, great knie, $30.

The best(read most versatile)outdoor knife I own is a $10 rough use knife I bought off the 'net. It would make gutting a deer sort of clumsy because of the size and shape, but believe me - it could be done. It will also chop/cut through small limbs and the like with ease. Good for clearing the brush on overgrown trails or clearing a path to get through the thick stuff. And I have no doubt that if it had to be used for defensive purposes, it would hold up well. The blade is pretty thick so it is very sturdy.
