During the World War 1 the British started a propaganda campaign concentrating on the German use of the sawback bayonet as another “act of frightfulness by the bestial Hun” and claimed their use to be a war crime as they believed they would leave horrific wounds.
Those featuring a serrated edge only made up 6% of the total number of bayonets issued. This WW1 sawback bayonet was reserved for NCOs, Pioneers, machine gun crews, and, most infamously, the storm troops known as Stosstruppen. It was a favorite amongst specialist units due to its effectiveness in cutting down bushes and barbed wire characteristic of the no-mans-land of WW1.
As a result of Allied soldiers began torturing and executing on-site any German soldiers captured with such weapons in revenge. Consequently, the German High command made a decision to recall all of the German sawback bayonets in 1917 and grind off the saw back edge before reissuing them to all units.
Sticky fire bombs for me, if you would be so kind
