Sanji fought against Wanze because as he put it, they were in a kitchen and his opponent was using food as a weapon. He only used the knives to cut the ramen and put them away when the armor was gone. As for Strong world, all of the Strawhats have used guns in that one. That being said, I think that was just their way of saying hello. Once the guns ran out of ammo they resorted to their tried and true fighting styles. I must have missed that part on Zou, I overlook details sometimes.
