Joe wasn't expecting the kick to the chest and flew into the air, but because blunt objects did very little to him, he quick recovered and grabbed his scissors again. Joe threw the scissors up in the air, and jumped up with them.
As he headed to Jin, it seemed like Joe was going to miss completely, too far behind Jin. But as Joe stuck the landing he grabbed for one of the handles making one of the scissor blades fly out in Jin's direction.
