Patent ID: 7716839

Claim:
A knife comprising: a handle having first and second side pieces coupled in a spaced-apart relationship and rotatable, relative to each other, around a first pivot axis between an open and a closed position; a blade coupled to the handle, the blade being rotatable, while the first and second said pieces of the handle are in the closed position, around a second pivot axis, relative to the handle, between an extended position and a folded position, and configured to be removable from the handle only while the first and second side pieces are rotated away from the closed position; and a fastener coupled to the second side piece and movable between an engaged position to rotationally lock the first and second side pieces in the closed position, such that the fastener exerts a clamping force on the first side piece for preventing the first side piece from rotating relative to the second side piece and a disengaged position to release the first side piece for rotation away from the closed position, with the fastener remaining coupled to the second side piece.
