I think the Grimm bones, if used to make weapons, would have been used like that in the distant past. Perhaps during the beginning of the Grimm Wars, there were Grimm bones being used to make weapons. I'd say that during the time Dust was discovered/invented, people started to move away from those materials and start making weapons from metal. It was easier to shape and it got the job done just as well as Grimm bones.
