Describe what your ideal spec's for a wilderness survival knife would consist of. YOU DO NOT HAVE TO CHOOSE AN EXISTING KNIFE. If there is a knife that you think is ideal (or close to it) then list it (with any modifications it needs), but otherwise I'd like to hear what features your ideal wilderness knife would entail.

FOR THE PURPOSE OF THIS THREAD YOU CANNOT SPECIFY MORE THAN ONE KNIFE. This exercise is suppose to challenge you.

ETA: I'll reserve my "ideal survival knife" specs until people have a chance to comment.
