My much loved KaBar Becker BK2. I have a...a few knives LOL--But when it comes right down to it, when the proverbial SHTF, this is still the first thing I will be reaching for! If you consider yourself prepping for what may come and you do not have a REALLY good knife, if you skimped, you are behind the 8-ball! I cannot recommend a knife for survival more, not at the price point! There are lots of good knives out there, I would also personally consider a Fallkniven F1 or a GSO-5.
