Discalibur

The Discalibur is a one-of-a-kind weapon used by Finis. Appearing normally as a sleek katana hilt, the Discalibur is in fact a highly advanced piece of Asterion Corporation technology, designed by Finis himself. It uses a combination of chemical processes, magic, and nanotechnology to convert the air in Finis' vicinity to a blade of unnaturally sharp, self-healing steel.
