Lying on the ground, getting hit in the head repeatedly, she knew she didn't have much time.  She had dropped her sword when he tackled her, but his was almost close enough.  As she punched him in the temple with one hand, she stretched and slid as best she could, something that was difficult given that someone was kneeling on top of her, and managed to grab enough of the hilt to pull it towards her.  She pointed the sword towards his head and stabbed him as hard as she could.  The sword was made out of the same material as his armor.  Hopefully that meant that it would penetrate.
