Finger Carving Seal

This is the jutsu that Jiraiya uses to send a message with, after his throat is caved in during the battle with Pain. The user concentrates chakra into their finger and using the heat from that can apply writing on whatever they want. This allows them to write on the skin of animals, iron plates, or a wide range of things however when doing so requires them to be very delicate with their chakra control. This jutsu causes slight discomfort for the target.
