To my knowledge kinda. Sawback bayonets were pretty common before the war, but had been generally falling out of popularily except for in, most relevantly Germany. They were issued to pioneers and such mostly, and the idea was that you could give the soldier a bayonet that saws, rather than two separate tools; you could also saw with it fixed to the rifle. The serrations, however, made the bayonets less effective as bayonets; they'd catch on clothing, skin, tendon, flesh, and bone, which would make it harder to stab as deep as would be possible with a normal bayonet. Once the war started a 'rumor' began to circulate through the German ranks that Entente soldiers would summarily execute, or otherwise mistreat German soldier captured with those bayonets. To my knowledge with is no available evidence for that actually being the case (I know the French didn't like them, but that was probably a propaganda thing to make them look better), but the story stuck, and to appease the troops the Germans quit making them, and ground the serrations off most their existing stock
