The big problem is this poor knife person is living in New York City, and one of the non friendly to firearm and knife cities people there is.
So it's no surprise the cards were stacked against him, it's just something that really has to be given thought about when living in cities like New York...
I found this knife maker and his and other videos on this Russian Facebook site.

Well hey ISIS it's against our UK laws to have knives so be warned ISIS you could find yourself under arrest.
