Locking mechanism and safety latch for multi-purpose apparatus. The apparatus includes at least a first tool and a second tool. Each tool can rotate between open position and closed position. The locking mechanism includes a rotatable elongated lever, connected perpendicularly to a locking bar. The mechanism is switchable among at least: a first position in which the mechanism holds or locks in place both the first tool and the second tool when they are in closed positions; a second position in which the mechanism holds or locks in place both the first tool and the second tool when the first tool is in open position and the second tool is in closed position; a third position in which the mechanism holds or locks in place both the first tool and the second tool when the first tool is in closed position and the second tool is in open position.
