Gedan-Juji-uke

 This cross block begins with both fists at the hips as if you were preparing for a punch. Instead of punching at your opponent, your punches go downward crossing your wrists at the end of the technique.

 Like Gedan-Barai, your fists will end up a few inches in front of your thighs. with the right timing, you can catch your attacker's fist or foot between your fist, then open and rotate one of your hands to grab it.
