If a street nigger pulled his malt liquor bottle away from his bumper lips and broke it on one of those nigger benches and then stabbed some caucasian people, that would be a good example of someone being nigger knifed.
Any object which is manipulated to be sharp enough to "shank" someone. Can be anything from a broken beer bottle, folded cash, wire and utensils. It is called a nigger knife because niggers can easily shank with the "nigger knife"
