A type of weapon that resembles a
bowling ball, but when you flip it it turned into a sword . Usually used in pairs. Often it’s not used intended style, people just throw it and it usually gets the job done, kills easily, but it’s original purpose was so that you could knock people out when it was closed, then flip it open to hold the blade against the unconscious person’s neck and threaten to end their lives for ransom money or another thing that you want. It takes
incredible practice and skill to wield
one of these without brutally injuring yourself, though.
