Meito

A Meito (名刀) is not a type of sword but rather the status of a sword.

In Japan, this means the sword has a history and is of legendary status. The blade is normally a quality blade which stands out above all other swords in its endurance and sharpness.

A meito is sometimes associated with the warrior who wields it and becomes part of his identity. Regardless of who owns them, a meito is regarded with highest respect in Japan and to be given a meito is to carry a great honour alongside it. Often warriors who lose in battle would have their meito taken from them by the victor, thus losing their honour alongside it as to lose a meito is to disrespect the honour of wielding it.

To wield a meito honorably, usually it would be passed down to them from master to pupil or from another family member. There exists several other methods alongside this which are acceptable but uncommon. Another method of gaining a meito honourably was to be offered it, this was usually out as show of respect from one person to another. A warrior may also win it in battle against another warrior in a fair duel and thus be allowed to claim it as their own.

To steal a meito or gain it using another dishonorable action is to show the meito disrespect and warriors who do so were often frowned upon. To put the status of a meito in a western style of thinking, a meito would be considered in status on par with swords like Excalibur (which would be regarded as King Arthur's "meito" in the Japanese sense).

One Piece
In One Piece, meito is often mistranslated as either part of the name of a sword (e.g. Zoro's Shusui is often recorded by fans as "Meito Shusui" instead of just "Shusui", ignoring the fact that meito is a status) or as a "renowned blade" (understandable given that if broken up, 名刀 gives 名 "renowned" and 刀 "sword").

Tashigi's dream is to free all the meito from the hands of criminals such as pirates. She believes the swords are crying because instead of being used for noble and honorable deeds, they are being used for criminal use. Her reason for tracking Zoro is to gain ownership of his meito, the Wado Ichimonji, which she believes is in the hands of a malicious person. As of Chapter 541, she has no victories over Zoro in her quest and, as far as readers know, while she has taken the sword Kashū - a sword not listed as a Meitou but still one of the Ryo Wazamono Grade Swords - she has taken none of the meito in her journey of Justice, while Zoro still possesses Wado Ichimonji and has also acquired Shusui.

Meito is translated simply as Famous Sword in the Viz Manga and Legendary Sword in the FUNimation dub.
