History

Traditional concealed weapon used by Shinobi and Kunoichi. A wooden peg or metallic finger ring with a spike hidden inside the palm amplifies pressure-point strikes and tears skin.

About

The spike facing into the palm or outward allows subtle pressure into nerve nodes (Kyusho), escape from grabs, and facial tearing without raising suspicion.
