Forged Destiny [Book 9: Ch. 16]

The scythe was made from Ironwood, that much I could tell. Not like I would have made it, or even forged by a Blacksmith at all; its shaft and blade were all one piece of metal without a seam. It had been grown that way rather than manipulated into position. I could tell with but a glance that it wouldn't last long in a fight. One, maybe two good hits or parries before the blade's head would be jarred loose. Of course, that wouldn't matter with Ruby. Her cripplingly high Agility meant any weapon she struck with was destroyed by the impact. And likely her target as well.

"Archmage Ironwood and I worked on this in secret," Ozpin said, ignoring my silence or just mistaking it for awe. In Ruby's case, that was accurate. "Though shaping a blade wasn't something that came easily to him, he was able to grow it roughly into shape. From there, it took time to file the blade. We used magical weapons from the vault for that. Our original efforts to make a scythe from those magical weapons ended in failure."
