ABSTRACT:
The present invention is a swim fin equipped with extendable knives which can be used by a diver to fight off an attack by a predatory underwater creature, such as a shark. The knives, when in their locked closed positions, lie in a recessed section provided in an outside edge of the swim fin. In their locked closed positions, the knives lie parallel with a bottom surface of the swim fin. When extended to their locked open positions, the knives point downward from the swim fin. The swim fin is provided with means for locking the knives in their open and closed positions, unlocking the knives from their locked open and locked closed positions, and moving the knives between their open and closed positions.
