The kunai, modest in form yet rich in history, is a word that plays its role in the Japanese lexicon of war and agriculture. The origin of this term goes back hundreds of years, and its meaning has evolved greatly over the centuries.
Etymology
The word “kunai” (苦無) consists of two kanji: “ku” (苦), meaning suffering, pain, or difficulty, and “nai” (無), meaning lack or non-existence. Although the etymology may suggest a negative context, in practice, kunai represents a tool of survival and adaptation, capable of turning difficulties into advantages. In the agricultural context, where the kunai had its beginnings, the name may reflect the hardships of farm work, but at the same time, the indispensability of the tool in the daily struggle for survival.
Humble Beginnings
The kunai began its life as an agricultural tool, used for digging and planting. Its simple, yet effective design meant that over time, it became a versatile instrument in the hands of those who could appreciate its potential beyond agriculture. In feudal Japan, where social status often defined access to weapons, the kunai became a valuable resource for those lower down the social ladder.
Shadow warriors, ninjas, adopted the kunai not only as a weapon but as a universal tool - for climbing, as a chisel, or even an improvised knife. 
Use of Kunai in Various Ways
The kunai, originally an agricultural tool, found its place in various aspects of life in feudal Japan, permeating through social layers from farmers to samurais and, most notably, to ninjas. Its versatility and accessibility made it an object of innovation in the hands of those who sought both simplicity and efficiency in their craft.

Scorpion...
Scorpion, whose real name is Hanzo Hasashi, is one of the most iconic characters in the Mortal Kombat series of games. As a specter from the netherworld, he seeks revenge for the death of his family and clan members, murdered by Sub-Zero of the Lin Kuei clan. This tale of vengeance is a central theme for Scorpion's character, recurring throughout many games in the series.
In Mortal Kombat, the kunai has become Scorpion's signature weapon. Over the years, his kunai has undergone several evolutions in terms of design and functionality:
▫ Film adaptations: In the Mortal Kombat movies of the 90s, Scorpion's kunai received a unique twist, becoming a living, snake-like creature that emerged from Scorpion's hand. It is difficult, therefore, to say that Scorpion used a kunai in the movie in the traditional sense.


The kunai appears in pop culture, including in many mangas and anime, often playing an important role in the arsenal of ninja characters or warriors. Here are a few examples:
▫ "Boruto: Naruto Next Generations": A continuation of "Naruto," where the tradition of using kunai by ninjas is continued by a new generation.
▫ "Ninja Scroll": A classic anime where kunai and other traditional Japanese weapons are used by ninjas in numerous fight scenes, showcasing their diverse application in combat.
Evolution of Perception
Kunai, though commonly associated with ninjas and their mysterious world, harbors much more history and applications than might seem at first glance. One interesting fact is that although today kunai is mainly associated with shadow warriors, in its beginnings, it was a tool used by a wide range of people, including farmers. Its simple, yet durable design made it indispensable in daily tasks, from agriculture to construction, demonstrating its versatility and practicality.
Additionally, contrary to popular belief and pop culture representations, the kunai was not primarily a thrown weapon. Its weight and shape were better suited for close-range combat and tasks such as forging or chiseling, making it a much more versatile tool than it might appear. The history of kunai is thus an example of how objects can change their meaning and perception depending on the cultural context and era in which they are used.
The contemporary appearance of kunai, both in the real world and in fiction, testifies to the remarkable ability of human imagination to transform simple tools into objects of deep cultural and emotional significance. From humble beginnings as an agricultural tool, through an invaluable element of the ninja arsenal, to an iconic weapon in the Mortal Kombat universe, the kunai has traveled a long journey, achieving legendary status. This journey does not just show the evolution of a tool, but the evolution of how we perceive such a tool through history and demonstrates how the past inspires contemporary entertainment and art.
