Nachdem wir in unserem anderen Artikel bereits geklärt haben, ob ein Katana is able to cut through steelwe would now like to know whether a katana can also cut through a real, flying pistol bullet.
Katana vs. bullet: the video evidence
The material of the projectiles
Heutige Munition besteht meist aus Blei oder Kupfer. Die Klinge eines Katana hingegen wird aus Steelmanufactured. Lead and copper are softer metals than steel. This makes it seem possible at first glance that a katana can cut through projectiles made of these materials.
The speed & the right angle
Jedoch schießt eine Kugel mit einer extrem hohen Geschwindigkeit aus einer Waffe. Bei Pistolen werden hierbei beispielsweise Mündungsgeschwindigkeiten von ca. 350 m/s erreicht, was 1260 km/h entspricht. Das Katana muss also in der Lage sein, dieser Geschwindigkeit beim Aufprall entgegen zuhalten.
Another decisive factor is the angle at which the bullet hits the sword blade. The bullet must hit the sharp side of the katana blade straight on. This is the only way to split the bullet cleanly, as the energy of the bullet hits the narrow surface of the blade. Otherwise the bullet would destroy the blade.
Conclusion
Cutting bullets with a samurai sword is possible under the right conditions. However, defence against bullets, as sometimes shown in films/anime, is not feasible in reality. In fact, firearms replaced swords as weapons in combat in ancient Japan.
