Each of the tools that ninjas were actually using back at the time had unique features and often served a multiple purposes. That was because ninjas had to not only combat enemies but also take on various other missions such as infiltrating enemy territories and collecting information. So they carried special tools suitable for the purposes of various missions. Here we have focused on such practical tools, particularly on the weapons of ninjas.
1. Shuriken [手裏剣]
Shuriken or throwing stars is almost synonymous with ninja. From windmill types to stick types, they were varied in shape. Ninjas sometimes poisoned the tips of the blades to make this weapon more deadly.
[Kashaken (火車剣): a variation of shuriken made explosive with gun powder]
2. Shinobigatana (Ninja Sword) [忍刀]
Ninjas were using their own kind of swords. Unlike longer and more curved samurai swords, ninja swords were straight and relatively short. They featured a large tsuba (hand guard) and ninjas sometimes stood their swords against the wall and used the tsuba part as a step when going over the wall. A string was attached to the scabbard so the sword could be collected from above the wall. These swords were also matte finished so they would not reflect light in the darkness.
3. Kunai (Dagger) [くない]
This double bladed tool was used not only as a weapon but also as a shovel, knife and a step ladder for wall climbing. It is versatile as the modern-day “survival knife”. When used as a throwing knife, it was collected with a string attached to it.
4. Makibishi (Caltrop) [撒菱]
Makibishi was scattered on the ground to wound and stop pursuers. Nails of a caltrop are arranged so one of its sharp nails always points upward however you throw it. It is believed that the plant seeds of water caltrops had been used originally for the same purpose.
5. Tekko-Kagi (Claw Dagger) [手甲鉤]
Tekko-kagi is worn on the hands to scratch enemy with its nails. It can also be used defensively against sword attacks and for various other purposes such as digging a hole in the ground and driving the nails into the wall when climbing.
6. Kusarigama (Sickle and Chain) [鎖鎌]
Kusarigama is a chained sickle with a balancing weight on the other end. Without the chain, it can be disguised as an ordinary farming tool. The weight part can be thrown at the enemy while the chain can be used to suppress the enemy before attacking with the sickle. But it requires a very high skill to use this weapon at will.
7. Fukiya (Blow Dart) [吹き矢]
Ninjas were using blow darts poisoned on the tips to assassin enemies remotely. The blowpipes were often disguised as a flute and carried along.
8. Metsubushi (Eye Blinder) [目潰し]
An easily broken bag or hollowed-out egg filled with pepper or chalk powder was thrown at enemies. It was used as an offensive weapon for its eye blinding effect, as well as to distract enemies when running away from them.
9. Shikomizue (Prepared Cane) [仕込み杖]
A sword blade plunges out suddenly from a cane which would never be suspected as a weapon. A ninja disguised as an old man could carry this weapon without alarming anyone.
10. Kakushi (Finger Brass Knuckles) [角指]
This is a kind of brass knuckles for ninjas. But unlike brass knuckles, ninjas wore kakushi with the sharp nails on the palm side and grab the arm or neck of an enemy tightly from behind to deliver a lethal attack. This weapon was perfect for assassination because it was compact to carry.
11. Toribiho (Flame Gun) [捕火方]
This weapon was used to project flames by igniting gunpowder and iron sand filled in the barrel. The technology at the time did not allow flames to reach very far, but it must have been stunning enough for enemies.
12. Tetsumari (Iron Ball) [鉄毬]
Tetsumari is a round weapon with spikes sticking out in all directions. When thrown at enemies, it could deliver a more lethal attack than shuriken due to its penetrative power. But the relatively large size was not ideal for carrying.
13. Nekote (Claw Dagger) [猫手]
This weapon was used by kunoichis, female ninjas. Kunoichis put them on their hands to scratch enemies with the sharp nails. The name “nekote,” literally meaning “cat hand,” comes from its shape like cat’s claws.
14. Shinobi Kumade [忍び熊手]
Shinobi Kumade is a kind of iron rake with collapsible pipe sections making grips. The string threaded through the pipes can be pulled tight to make a long spear-like weapon while loosening it will make this weapon like a nunchaku.
