History is chock-full of savage samurai and ninja life-ending hardware; if you think they were limited to throwing stars and katanas, it's time to get schooled.
While plenty of ridiculous weapons have been laughed out of the history books, the weapons ninja and samurai used are almost exclusively ferocious. Some of the most famous weapons of all time belonged to samurai, but of course, their deadliest tools are only spoken of in a hushed tone.
You may know the Sai, but you probably don't know the Kusarigama, and most people fail to realize how many different types of throwing stars exist.
The Kyoketsu-shoge is a nasty little devil with two blades: a double-sided main dagger as well as a hooked edge jutting off the hilt.
The knife is attached to a cord with a ring on the end, allowing the wielder to wrap an opponent and pull them into dagger range. The user then cuts their adversary's throat with the curved edge and follows through by thrusting the straight knife upward into a vital spot.
The weapon evolved from a farming tool and provides utilities beyond slaying; it can also be used as a climbing aid (assuming the cord is strong enough to hold an adult).
The Kusarigama is a compound weapon made of a kama (sickle) attached to a kusari-fundo (a heavy chain with a weight on the end, usually made of iron).
The art of wielding one of these is so advanced that the practice has its own name: kusarigamajutsu. This weapon is essentially the deadliest lasso on the planet; the wielder swings it over their head before wrapping their opponent, making them easy prey for the sickle blade.
The Shuko is a multifaceted tool consisting of a small metal plate that sits atop the user's knuckles with four spikes (or claws) on the underside that jut from the palm.
In addition to slashing faces, they can also be helpful for climbing, especially when used in conjunction with similar foot spikes.
The Kaginawa is ostensibly a grappling hook, which is sort of cool. But these things also feature thick, gnarled hooks that make them double as deadly weapons. There are usually four hooks on the end of a long rope, which can obviously do damage to a person (in addition to helping ninja scale walls).
