Uncle in Germany during ww2, killed an ss-officer With his own boot knife, there was a little leather strap inside boot that held the 39, model Bayonet, but only for ss officers who did not carry a rifle that much. Guy walked in his front door and my uncle and three others were already in the house he had. All were hiding and he sat right in a stuffed chair that Uncle was behind, so as soon as he took one boot off and put it next to side of chair, then put knife in strap, Uncle slit his throat with ss guys own Bayonet. Sneaky and smart, both sides. But Germans thought they were invincible, Uncle used to tell me all the time.
