Kogai and Kozuga

The samurai were amazing warriors, but their main task was spying and espionage. Their teachings and the art of fighting corresponded to this. The samurai's equipment included the art of inaudible movement and invisible movement. Their weapons also had to adapt. These were multifunctional and one weapon easily replaced the other two. The samurai sword scabbards were also very well thought out. Of course, they hid swords, but they also had small pockets for coins or additional knives. These included Kozuka and Kogai. The samurai carried them in their scabbards with their sword and used them in situations where it wasn't possible to use such a long sword.
