Jokoto

Weapon (shortsword or longsword), rare

This early predecessor of the katana is of east Asian design. These straight, single-edged, steel blades are forged and sharpened through a ritual that is much more time-consuming than traditional methods, but produces a superior weapon. The Jokoto of the Han dynasty are characterized by an ornamental ring on the pommel, that sometimes also bears the crest of a particular faction or military unit. The sword is incredibly sharp, light, and easy to wield.

You gain a +3 bonus to attack and damage rolls with this magic weapon. Additionally, while you wield this weapon you can speak, read, and write Chinese.
