Dojikiri Yasutsuna F4

Description:

A Photon Sword, one of the few close combat weapons available in GGO. The letter in the name indicates the length of the blade, while the number denotes its color. Slightly underpowered compared to similar blades, its main strength is its lightness, making it easy to aim straight for enemy weak points. That doesn't mean it can't string, though, as it has a high critical hit rate
