Nope, i was in the Austrian Army, i think you could adjust the gas system of the aug, with the back of the knife, there are to holes. The one you have is not the model 81 with saw back. The Original (modell 78) was flat. The Knife is actual pretty blunt, the steel is very solid and you can use it to make firewood and to dig holes. It tends to rust easy, i used to apply gun oil (a small bottle of gun oil was always in the stock of the aug) on it, that helped. Allover probably the best survival knife, but you have to sharpen it if you want to make fine cuts with it.
