Amazing Butterfly Knife Bottle Opener [VIDEO]

When I was a kid I used to ride my bike all the way to a store that sold Chinese weaponry.  I don't know how I convinced them to sell it to me but I did.  Everything from butterfly knives to throwing stars.  So when I saw this butterfly knife bottle opener, I got a little nostalgic. 

This one is the best one that I saw, there are other clunkier versions, but this one is black and really takes bottle opening to a new level.  I guess this kinda fits the Throwback Thursday theme.  I want to get one and use it on my next bottle of root beer!
