Ninja tools refer to the various weapons and equipment traditionally used by ninja, the covert agents of feudal Japan. These tools include items like shuriken (throwing stars), kunai (daggers), and smoke bombs, which were designed for stealth, agility, and surprise during missions. In addition to weapons, ninja tools also encompass climbing gear, such as grappling hooks and climbing spikes, which allowed ninjas to scale walls and escape quickly. These tools were essential for their roles in espionage, sabotage, and guerrilla warfare, enabling them to navigate their environments effectively.
