I am trying to decide on a blade to carry for not only general use, but one that would also be useful in survival situations. It would have to be a "legal" folder - ie: 4" or less, single edged and not an auto. I have read a number of reviews of "survival knives" of one sort or another. Most seem to have been written by knowledgeable folks and many include impressive looking field tests.I have also read with interest many of the postings on this forum - also from lots of guys who sound like they know what they are talking about. I am curious, however to hear about any actual use of a particular folder under real survival conditions. Has anyone HAD to use one to get out of a plane, build an emergency shelter, hunt for a meal, etc. Any feedback - positive or negative - on particular brands/models would be most appreciated. Thanks!
