OniSlasher is Blacktails' weapon of choice. OniSlasher is made of a special metal called Zorite which cannot be broken and can break other metals with ease if enough force is applied.
OniSlasher has a Demon trapped in it with the same name, he appears as a black wolf with red markings and green eyes. He stands a good 7 feet tall and wears black pants and a dark red leather trench coat.
This demon can at times come out of the blade but must remain within a 15 foot radius of the hilt in which he is trapped.

On occasion the mouth of the wolf on the hilt will move and the blade will indeed speak. His voice is deep and a little raspy.
