Just gonna throw this out there, the swords used are monomolecular blades. The edge of the blade is (At it's thinnest) a single molecule in width which, when all the force of the swing is focused on that edge, makes it amazingly strong/sharp.

Science yo'. For the bow? It's omni isn't it? Mass effect duct tape...
