Será que uma katana corta um elmo viking? Teste com resultados surpreendentes!

This video showcases the extreme durability and cutting power of Cold Steel's Warrior series katanas. The Warrior Katana demonstrated impressive performance on bone and rope, while the Warrior O Katana and Nodachi proved capable of severing multiple carcasses and even piercing a car hood. The Chisa Katana's heat treatment was validated through a 45-degree bend test.

This video delves into collecting WW2-era Japanese samurai swords, distinguishing between machine-made and handmade blades. Key identification points include the scabbard (Army vs. Navy Type 97), the Hamon (temper line), and Hada (steel grain). The tang's markings, such as the Army 'Star' or Navy 'Half-Chrysanthemum' stamps, indicate production quality and value. Condition is paramount for collector value, with prices ranging from $800 for machine-made to over $3,200 for high-quality handmade pieces.

The Type 95 Shin Gunto was a mass-produced NCO sword for the Imperial Japanese Army, adopted in 1935. It mimicked traditional katana styles but used machine-made components like cast aluminum handles and steel blades without a hamon. Variations exist in arsenal markings (Tokyo, Nagoya, Kokura) and construction details, with late-war examples simplifying materials due to resource shortages.

This video explores the practical application of katana and other edged weapons for self-defense, emphasizing core combat principles over specific tool mastery. Officer Jared Wihongi, a SWAT operator and combatives instructor, demonstrates how techniques for staffs and knives translate to swords, highlighting the importance of angles, thrusts, and footwork. The review covers specific models like the Ronin Forge Dojo Pro #3 and Cheness Nagasa, offering insights into their handling and effectiveness.

This video offers a first impression review of a Cold Steel Katana Warrior sword. The presenter expresses enthusiasm for the blade, calling it "as deadly as it gets" and a "must-have." The video also promotes a "Gun & Knife Forum" hosted at weaponseducation.net, encouraging viewers to join for discussions.

This video explores the intricate process of forging a blade, specifically focusing on the creation of a katana. It offers a glimpse into the traditional craftsmanship involved in producing such edged weapons. The Royal Armouries, the UK's national collection of arms and armour, presents this behind-the-scenes look, inviting viewer questions about their extensive collection and the history of arms and armour. The content is educational and showcases the artistry behind historical weaponry.

This video explores the theoretical and practical outcome of loading a 50 BMG cartridge into a 12 gauge flare gun. The experiment, conducted by a hobbyist, demonstrates that while the 50 BMG cartridge surprisingly fits, the flare gun's firing mechanism and primer strength are insufficient to ignite it. The test highlights the significant differences in primer resistance between ammunition types.

This video debunks the myth that shooting upwards is safe, explaining the lethal terminal velocity of falling projectiles. It showcases the Canik Mete MC9 Prime with a Gideon Valor optic and demonstrates the use of 9mm shot shells for controlled, less dangerous demonstrations, highlighting their unique projectile dispersal.

This video debunks the myth that a .50 BMG round passing near a target can be lethal due to shockwave. Using a ballistic mannequin head and a Big Kahuna Firearms Raptor-50 rifle, the test demonstrated that while the .50 BMG round impacted and destroyed a concrete block behind the target, it did not affect the mannequin or the cardboard placed near it. The conclusion is that a near miss from a .50 BMG is not fatal.

This video conducts a destructive test comparing the impact of .22 LR and .50 BMG rounds on a ballistic head model. The .22 LR caused minimal damage, while the .50 BMG completely destroyed the head, highlighting the vast difference in energy and destructive potential between the two calibers. The test also showcases the Raptor .50 BMG upper receiver as an accessible way to experience .50 BMG ballistics on an AR-15 platform.
