Abstract: A double-bladed combat weapon includes a handle having slotted ends. A knife blade having a semicircular tang, which has a plurality of index notches, is pivotally disposed in each slotted end of the handle. An indexing mechanism is disposed in each end of the handle and engages one the index notches of the blade tang. A release for each blade is provided to permit the user to swing the blades selectively from a rearwardly directed position to a forwardly directed position, as well as intermediate positions during combat.
