Swords

A sword is a long edged weapon, used in many forms by various civilizations throughout the world. The word sword comes from the Old English sweord, which cognates to Old High German swert, Middle Dutch swaert, Old Norse sverð, Swedish svärd, Old Frisian and Old Saxon swerd and Modern Dutch zwaard, from a Proto-Indo-European root *swer- "to wound, to hurt".

A sword fundamentally consists of a blade, with one or two edges for striking and cutting, a point for thrusting, and a hilt for gripping. The basic intent and physics of swordsmanship remained fairly constant down the centuries, but the actual techniques varied among cultures and periods as a result of the differences in blade design and purpose. The names given to many swords in mythology, literature, and history reflect the high prestige of the weapon.

Swords in One Piece and their Classifications
Swords are a very common weapon in the world of One Piece. Many people wield swords, but there are those who train hard, and learn to use swords exceptionally well. These people are known as swordsmen.

Swords are used throughout One Piece by various Swordsmen and come in different grades.

Katana
The Katana is a type of Japanese sword. Tashigi's Shigure, is a Katana.

Daito ("Long Sword")
Rather than a specific weapon, the Daito is actually a category of blades under which both the katana and tachi fall. To qualify as a daitō the sword must have a blade longer than 2 shaku (approximately 24 inches or 60 centimeters) in a straight line. In the case of Roronoa Zoro, all three swords that he uses for his Santoryu are all confirmed as Daito katanas.

Nodachi ("Field Sword")
The Nodachi is a large two-handed Japanese sword. Compared to the katana, the nodachi was more difficult to wield due to its size and weight, but - like any weapon - could be extremely deadly if the warrior wielding it was skilled. The length of the nodachi's hilt varied between twelve to thirteen inches (30 to 33 centimeters). Its cutting capability and range exceeded that of a katana, due to its weight and size. The captain of the Heart Pirates, Trafalgar Law wields one of these.
