As your second kunai hits your first kunai, i throw my own kunai with my right hand, which hits your first kunai thereby changing it's trajectory from hitting my head, to cathing your second kunai in the hole ring thingy, causing it to be nailed to the ground and stopping it in it's tracks. While i throw my kunai, a shield begins to grow forth on my left arm, it looks kinda like this.

Though a little shorter in both ends, so it doesn't restrict my movements the slightest. The shield is as hard as i can make it. As you try to slize my ribcage open, i place my shielded forearm in a vertical angle in your blades path with a lightning fast movement, causing it to stop with a loud noise. As the sword makes contact i tilt my shielded arm more to the left while leaning my body backwards, this gives me anough room to do a hick kick that'll hit you under your chin and send you flying backwards.
