Ruby watched on the thermal view as the savage grabbed her Bo, and began to swing it at her, level to where her ribs were. While the metal staff had a heat signature almost equal to the dojo's air, she could see the man's hands, grasping her staff, and she knew how long the weapon was while extended, so she could approximate where the end of the Bo was. 

As the staff almost hit her, Ruby did not dodge. Rather, she used the hilts of the knives as a barrier between her hands and the metal rod, catching it, and twisting it around, attempting to disarm the savage. However, if the maneuver succeeded, she would again, drop the staff, and dash towards the savage in a serpentine manner, and perform a low cut aimed at his midsection. 

If the force with which the man struck was too much, then Ruby would roll with the blow, allowing herself to get pushed back, so she didn't drop her knives, or get knocked off balance.
