When people imagine a ninja, the weapon that almost always comes to mind is the iconic curved blade. However, the question "what are ninja swords called" is not as simple as it seems. While the modern pop culture often uses the term "ninja sword" as a catch-all, historically, these warriors utilized a specific and sophisticated tool designed for their unique craft. The primary answer is the ninjato, a distinct blade characterized by its straight length and square guard, though the reality includes a spectrum of specialized tools.
The Myth of the Katana
To understand what ninja swords are called, one must first address the most famous Japanese sword: the katana. The katana is a legendary curved, single-edged sword synonymous with the samurai class. Forged using advanced metallurgical techniques like differential hardening, it was a weapon built for cutting through armor and delivering powerful, decisive strikes. Because of its prominence, many assume the ninja simply used a cheaper or inferior version of the samurai's katana. This assumption, however, overlooks the specific tactical needs and historical reality of the ninja's role.
Introducing the Ninjato
The most direct answer to "what are ninja swords called" is the ninjato. This blade is often described as the anti-katana due to its design. Unlike the katana, the ninjato has a straight blade and a relatively short length, usually measuring around 24 to 30 inches. Its most distinguishing feature is the square or rectangular guard (tsuba), which differs from the ornate, curved guards found on samurai swords. The straight edge was not a sign of inferiority but a pragmatic choice, allowing the ninja to thrust the blade straight through targets or hook and pull down roof tiles and branches, which was essential for the espionage and sabotage central to their missions.
Design and Functionality
The design of the ninjato was a direct reflection of its intended use in stealth and subterfuge. The straight blade simplified manufacturing, making it easier to produce quietly and without the specialized facilities required for forging a katana's complex curve. Furthermore, the straight edge was ideal for climbing; a ninja could slide the edge of the blade into a crack in a wall or rock face and use it as a makeshift ascender. The sword was less about dueling and more about utility, serving as a tool for survival, escape, and silent dispatch in close quarters where a longer weapon would be cumbersome.
Beyond the Blade: The Ninja's Arsenal
While the ninjato is the iconic "sword," a complete answer to what ninja swords are called must acknowledge that the ninja's arsenal was diverse and pragmatic. They rarely relied on a single type of weapon, instead choosing tools based on the mission's demands. This versatility means that the term "ninja sword" can sometimes refer to other edged implements that were more practical for certain tasks than the ninjato itself.
Specialized Tools of the Trade
Kusarigama: A sickle attached to a chain with a heavy weight at the end. It offered reach and versatility, capable of entangling a sword or striking from a distance.
Shuriken: While often called throwing stars, these were primarily distraction tools. They were used to impair an opponent's vision or movement, creating an opening for the ninja to close in or escape.
Tanto: A small dagger or knife. Easy to conceal, the tanto was a last-resort weapon for close-quarters combat or as a tool for silent killing.
Kunai: A pointed tool originally used for masonry or gardening. In combat, it could be thrown or used as a dagger, and its weighted handle made it a reliable throwing weapon.
