The ANTIFA are selling a knife that looks and is the same dimensions as a credit card. It has the ANTIFA logo on it so it can be left behind as a ‘calling card.’
The blade is only like two inches but is razor sharp like a razor blade. Probably for slashing their unsuspecting and innocent victims.
The knife clicks together buy removing the blade from the housing and clicking the two parts of the housing using the protruding nodes into their correspondent couples.
