User blog:RWBY Adam Taurus/Melanie and Miltia

About the yellow trailer, I have notice melanie and miltia that there is something strange about their weapons. Because, all of the RWBY weapons can shoot bullets right ??? except to melanie and miltia's weapon, and why melanie and miltia's weapon are not upgraded. It is just a simple weapon with a claw and blade boots that is use in the century when were bullets are not yet created.
