Bladebane armor

In the RPG
Suits of this form of half-plate armor were originally seen among the orcs, where they were used by leaders of great renown. The humans eventually copied the design. The surface of all exposed plate sections is decorated with raised images of warriors involved in glorious battle. Orcish bladebane armors, naturally, show orcs at war, while those suits produced by humans depict powerful knights striking down thier foes. No self-respecting human or orcish warrior would consider wearing armor created by the opposing race.
