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. Throughout One Piece various Swordsmen come in different grades and types. Some of these swords they wield are named and are even classified as "meitou".

Katana
The katana (刀) is a type of Japanese sword. It is a single-edged, curved blade that was used by many samurai. Pronounced as "kah-tah-nah", both katana and katanas are acceptable as the plural forms. Tashigi's Shigure is a katana. The katana length is between 60 to 73 centimeters.

Daitō
Rather than a specific weapon, the daitō (大刀) 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
The nodachi (野太刀) 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. Nodachi's length can reach the 1.50 meters. The captain of the Heart Pirates, Trafalgar Law wields one of these, to be used in conjuncture with his Devil Fruit powers. Shiliew, former Chief Guard of Impel Down, also wields one.

Cutlass
A cutlass is a short, thick saber, with a straight or slightly curved blade sharpened on the cutting edge, and a hilt often featuring a solid cupped or basket-shaped guard. Best known as the sailor's weapon of choice, the naval side arm, likely because it was also robust enough to hack through heavy ropes, canvas, and wood. It was also short enough to use in relatively close quarters, such as during boarding actions, in the rigging, or below decks. Many low-ranking Marine soldiers and pirates are shown to be wielding one of these.

Saber
A saber is a type of sword with a single edge blade with a large hand guard. Its blade is usually (but not always) curved of variable length. Unlike a cutlass, the saber is longer and thinner in design. Sabers are often seen being used by background characters. The most notable use of one is by Shanks, who seems to favor them over other sword types. His saber seems to be larger than a normal one.

Kukri
The kukri is a heavy, curved knife used for both as a tool and a weapon. It is slightly deflected at an angle of 20°, though some examples have a very steep angle. The kukri starts with 3 to 10 centimeters, the length is 30 cm onwards, tapering towards the edge from the broad upper margin. It almost always has a single edge and almost never has a "false edge". It usually has a very thick spine and in many ways is a hybrid between knife and axe. The "Big-Knife" used by Sarquiss resembles a kukri, and Helmeppo uses two kukri for combat.

Shikomizue
A shikomizue (仕込み杖) is a sword normally concealed inside a cane or walking stick. It became popular when katanas were outlawed. Brook has been seen wielding one for his Fencing Style, and Roronoa Zoro also used one in an anime-only flashback.

Knives
A knife is a small single bladed tool used for cutting things with. A knife has come to be seen as a eating tool, but it can be used for many things. Because of their size, they are easily concealed and can be used as weapons for fighting with.

Sanji has been seen using knives for cooking as well as calling them a chef's soul. Buggy carries many knives with him, including hidden within the soles of his shoes. Other pirates and people carry knives for combat or other purposes.

Axe
An axe is a heavy curved blade attached to the end of a stick, and it can have the blade on either one or both sides. They can be used for tools, such as chopping down wood, or as combat weapons. There is also the "Axe Dial", which produces a burst of very sharp slicing air that can split a man in two.

Morgan has an axe installed as a prosthetic right hand, earning him the nickname "Axe-Hand". X. Drake also uses a four-bladed axe, each blade going in one of four cardinal direction. Other notable axe users include Brogy, Sentoumaru, Blue Gorillas, and Ronse.

Spear
A spear is a sharp point attached to the end of a long pole, creating a long-ranged blade weapon. Though most spears are meant for piercing, some have blades at the end for slashing purposes as well. Since spears have a much longer range than an average sword, it is said that a swordsman would require three times the strength to beat a spears-man.

Boa Marigold, Catarina Devon, and the female member of the Giant Squad each wield a spear. Hannyabal uses a variant of the spear, a Japanese halberd with a katana-blade on each end named Kessui. Edward Newgate uses a bisento, a much heavier version of the naginata.
