The aircraft carrier

You catch him off guard and attempt to hit him with a jab with your screwdriver from the right. He blocks it with his forearm at the last moment and grabs your upper (screwdriver wielding) arm with his other hand. The forearm he used to block your initial attack he uses to hit your jaw, bending your screwdriver arm down. With the hand he hit you with, he tries to wrap his arm around your wrist and grab the screwdriver, but you're too fast. You stab him in his side and leave the screwdriver in his side. With your hand now free you use that hand and your other one to grab his opposite arm and twist his body while throwing him on the ground. You keep him pinned with your foot while stabbing him several times.
