Corsair's Edge is a Light Blade in Golden Sun: The Lost Age. It is found outside Lunpa's house in Lemuria. However, it is a Rusty Sword, and must be reforged in Yallam. As a Light Blade, Corsair's Edge can be equipped by Isaac, Felix, Garet, Jenna, Ivan, and Piers. It increases the wielder's attack by 90. It can be bought for 6300 coins and sold for 4725 coins.
Corsair’s Edge's Unleash effect is Lunar Slash. Lunar Slash converts all damage to Jupiter damage and attacks with an additional 25 damage points. Also, it may decrease the target's elemental resistance by 40 (it can be further lowered to 80). Visually, Lunar Slash resembles the attacker jumping into the air and swinging Corsair's Edge, with a large slash cutting across the screen, much like the Sea Fighter's monster skill, Echo Cut.
Corsair's Edge is surprisingly weak considering when it can be obtained. Stronger weapons will most likely already be available, such as the Mist Sabre and the Cloud Brand. In fact, this weapon is essentially a weaker version of the Ninja Blade, which can be purchased in Izumo. If stronger weapons aren't in the party's inventory, they can be received from the Lemuria Spring. As a result, Corsair's Edge will not see any practical use.
The word "corsair" is generally in reference to a French privateer, although it is also used as a more flamboyant or romantic word than "privateer" or "pirate." This reference probably has some association to the location it is found, Lemuria.
