1) Damascus Sword

(Ancient times-18th century, India)

The Damascus sword was produced in India and other areas in Asia as early as 2,000 years ago. Ancient craftsmen used wootz steel, a metal laced with carbon nanotubes.

Early Damascus blades contained as much as 1.5% carbon. 

The iron ore used to create these blades was found in Indian mines and utilized until the 18th century, when much of the knowledge of Damascus steel was lost. 

Damascus steel swords could stay sharp throughout several battles. Some blades proved so sharp that they may have been able to cut falling silk and slice stones in half. 

Damascus steel likely sounds familiar to you. That’s because it has experienced a major boost in popularity over the last several years as modern bladesmiths have learned the ancient forging technique and experimented with new ways of forging Damascus steel products. 

2) Shamshir

(16th century, Persia/Middle East)

The shamshir is a curved sword produced and utilized in 16th century Persia, the greater Middle Eastern region, and parts of Mughal India. Recognized for its dramatically curved blade, the shamshir is an ultra-sharp historical blade made with Damascus steel. 

Many swords fall under the “Damascus sword” category described above, and the shamshir is just one deadly example. The shamshir is characterized by its unique blade shape and tapered construction. 

The sword was used by soldiers fighting on foot and on horseback and was effective in both scenarios. 

Merchants and soldiers traded shamshir swords widely in the 1500s, and the shamshir became a popular weapon across the Middle East as a result. 

Today, you can find historical examples of shamshir swords in many museums around the world. Reproductions of this sharp and deadly sword keep its legacy alive. 

3) Wakizashi 

 (15th-16th centuries, Japan)

The wakizashi sword was first developed in Japan during the Muromachi period (15th to 16th centuries). This sword was the back-up weapon of the fierce military nobility called the samurai. 

Slightly smaller than its famous counterpart the katana, the wakizashi’s blade measured 12-24 inches long on average and was forged with a slight curve. 

This sword was similar to the katana in many ways, but is not merely a smaller version. The wakizashi is known for its extremely sharp blade and its unique capabilities. 

Although a secondary weapon, the wakizashi proved essential in close combat and indoor fighting. The short and maneuverable blade was deadly to both enemies and samurai, as it was used not only for fighting but also for ritualistic suicide performed by some samurai. 

Unlike the katana, which could only be wielded by the samurai, wakizashi swords could be worn and used by the merchant class. Merchants needed protection when traveling with valuable goods, and the wakizashi’s small size and sharp blade made this weapon a perfect choice for merchants.

Japanese bladesmiths forged wakizashi swords like the larger katana. Production methods included differential heat treatment, multiple blade foldings, and the use of high-carbon steel. 

4) Katana

(700 AD-present, Japan)

The katana is Japan’s most famous sword. Thanks to movies, tv shows, and books, the katana is one the most recognizable swords in the world. This blade is the source of fascination for history enthusiasts, bladesmiths, and fans of Japanese culture. 

The katana appeared in its earliest form in the 700s AD. The early style of the blade was based on the Chinese double blade, but Japanese swordsmiths altered the katana to make it unique. 

While the katana can be traced back to around 700, the sword was not widely used by samurai until the Kamakura period (1185-1333). It was the primary weapon of the samurai class and was paired with the smaller wakizashi. 

The quick draw time, sharpness, flexibility, and durability of the katana made this weapon the perfect choice for samurai. It was only wielded by these fighters. 

Japanese swordsmiths forged the katana from several bars of iron to give the swords their distinct physical characteristics. A soft bar gave the sword flexibility. Two hard bars provided strength. A steel bar provided an edge for sharpening. These bars were heated together and hammered into a single deadly blade. 

While not the sharpest sword on the list, the katana’s design made it an extremely effective blade. Its combination of flexibility, durability, and sharpness is unmatched by other swords throughout history. 

The katana was used in combat until the end of World War II. After a period in which production was banned, swordsmiths across Japan have again taken on the challenge of creating beautiful katana swords for collectors. 

5) Kilij

(3rd century, Turkey)

The kilij is considered one of the best cutting swords in history. Derived from the word “to kill,” the design of the kilij dates back to around the 3rd century BC and was an important weapon to the Turks and other people groups of the region.

Although the design of this sword is ancient, the kilij in its most modern form was developed sometime during the 15th century. It enjoyed a long history of use the saber used by Ottoman Turks. 

During the Napoleonic Wars, Europeans caught on to the power of the kilij and adapted it for their own military purposes. 

The kilij is similar in shape and size to the scimitar. It features a single-edged, curved blade and unique construction. 
More metal was added to the end of the blade, increasing its mass and momentum and making it a deadly cutting weapon. 

The kilij proved most deadly when used on horseback, but was less effective in dueling due to its weight and length. 

6) Gladius

(3rd century BC-3rd century AD, Roman Empire)

The gladius was the primary weapon of the Romans during the early expansion of their empire from the 3rd century BC to the 3rd century AD. 

Double-edged and two feet long, this short sword proved effective at cutting, slashing and especially thrusting due to its carefully considered shape. The blade of the gladius featured a tapered end that could wound or kill opponents easily. 

The short length of the blade also made the gladius highly maneuverable in combat. Although many reproductions of the gladius feature rather plain hilts, the swords of officers and other high-ranking Romans would have been ornate. 

A few types of gladius swords were produced through Roman history: Gladius Hispaniensis, Mainz Gladius, Fulham Gladius, and Pompeii Gladius. Out of all of these variations, the Pompeii Gladius was the most popular. 

Although not the longest blade on the list, the Roman gladius was truly a sharp and menacing weapon.

7) Falcata

(Pre-Roman Iberia)

The falcata was an Iberian sword used in battles against the Romans during the Punic Wars. The sword featured a single-edged, slightly curved blade that narrowed and then widened toward the end.

The shape of the falcata was the key to its success against the Romans. Because of its curved design, the falcata had more mass towards its tip. It thus had the speed and maneuverability of a sword and the chopping power of an ax. In addition, the blade of the falcata was pointed, making it an excellent weapon for thrusting.
