After weaving the needed hand signals, the user manipulates pre-existing metal around them to form a complex drill that overs their arm from elbow to finger and a short distance beyond. The drill has different parts that spin at different speeds and in different revolutions. This enables the drill to deal progressive and severe damage upon impact, mostly starting with piercing. This technique is a great assassination and execution technique. It can also break an opponent's guard. The drill can be left not spinning to use a simple spear. The only downside is that the drill weighs at least thirty pounds, making it somewhat heavy.
