 CONT: Weaver kills the German soldier who is about to shoot Miller,  who is hanging in a tree by his parachute, by throwing a switchblade  into his back. Besides the fact that switchblades are poorly  balanced and utterly unsuitable for throwing, Weaver joined the team  after escaping from the custody of several MPs, who would presumably  have disarmed him upon his arrest, leading to the question of where  the knife came from.
