That's the scary knife that was thrown? lol. That looks like some crappy knife a jackass would pick up from a convenience store. I doubt it weighs more than 2 ounces
I throw knives almost everyday. Fun hobby. I can easily stick them from varying random distances, but throwing knives in a real fight should only be used as a diversion. I have knives that weigh over 16 ounces that may sink into wood about an inch, when a 22 round would blast right through it, and that's IF the point hits first. The realistic value of a thrown knife is about what a steel bar at equal weight would inflict.
One random person throwing a knife is not worth a headline. Tell me when 30 or more protesters show up with firearms.
