The real point is (no pun intended!) that German soldiers believed they would be badly treated if found with a sawback. Like the babies spitted on a bayonet, the 'terrible' sawback bayonet and the wounds it inflicted, often after the bayonet had been purposely covered with faeces, was Belgian propaganda put out to counter the fact that the Belgians were still in the public eye for their treatment of the natives in the Congo, which included, inter alia, double hand amputations
Anyway, the German General staff managed to stiffle that belief, common in the first 12-18 months of the war only, after researching the matter. But the belief was resurrected in 1916 or so presumably after the S.84/98 - many with sawbacks - started to become the bayonet of choice for trench-raiders. Hence the order to remove the sawbacks from all front line troops and then the de-sawbacking for re-use there.
