This Ukrainian grand dad was a KGB (and then Ukrainian Security Service) general. Even that he is pretty old he still has some skills and someone has got him on video so we decided to share this video with you. He says those are normal
AK-47 knives, "nothing special, just regular non-modified AK-47 bayonet knife". I am not sure exactly of his age, but this man is Konstantin Siry - was an Ukrainian anti-terrorist center officer. People call him "legendary".
