Spearhand Thrust: This attack starts with the attacking hand from the cover position generally. The attacking hand will open to the position commonly known as shuto (knifehand) but it will not attack with the outside. Nukite signifies the fingertip region. So the attacking hand thrusts out from cover with the hand open and attacks generally the spot just above the chest at the lowest part of the neck or at the solar plexus. Both positions are soft and the Nukite will generally penetrate deeper than a Seiken Zuki in small areas surrounded by bone.
