With the new Rambo movie in theaters the knife world needs to brace itself for a new rush of customers who will want to get a hold of the classic survival knife that was prominently featured in the first three films. Of all the military knives on the market, the survival knife is probably the most popular due to its innovative concept. For those not familiar with the classic survival knife, it is a knife where the top of the handle unscrews revealing that the hollow handle acts as a glove compartment of sorts where vital camping or survival items such as matches, fishing life, a knife sharpener, et al can be stored. While survival military knives have become the butt of pop cultural jokes, there are a number of benefits that the survival knife offers and this is why it still remains on the market. If you want to safely carry items that are necessary for an outdoor excursion – to say nothing of also acquiring a reliable cutting instrument – then owning a military survival knife becomes a smart purchase.
