Octa Grab is a double grab where you right hand grips the tail of the right ski and your left hand grips the front tip of the left one. Lift your knees closer to your chest. Reach with your left hand to grab the ski outside near the binding, while reaching the right ski with your right hand from the inside. Now, if you have enoght time to finish the trick, slide your both hands like your doing a high mute.
