Unlike lesser films that just advise you on how to not get stabbed (which, to be fair, is still a pretty useful skill), Surviving Edged Weapons attempts to explain the entirety of "knife culture." For the most part, that takes the form of alerting policemen that people from other countries (mostly Canada, from the sound of things) sure do like to stab people a whole hell of a lot, but occasionally they try to get a little deeper into the psychology, starting with a three-minute caveman murder mystery. Two things make this amazing:
Well, three things, if you count Oog's magnificent mane.
First, this is a police training video, so the fact that it takes the time to show how to deal with knife-wielding cavemen means that someone thought this was an important thing to show rookies. Clearly, SEW is secretly training cops for time travel, something that I am glad my tax dollars are supporting.
Second, this is how the movie opens, by going all the way back to "the dawn of man." The next thing that happens is that a guy gets run through by a sweaty meth addict with a longsword. And it only gets crazier from here.
The sweaty, mustachioed face of knife culture.
