This video tests the penetration capabilities of knives against a ballistic vest. It demonstrates that even with a hard armor plate, a knife can penetrate to a limited degree, with the Tecto Hanv knife penetrating about 1/4 inch and the A3 Delta knife penetrating deeper. The video suggests that for stab resistance, hard armor is preferable.
This video tests the stab resistance of hard body armor against two different knives, the TEO Hum V automatic knife and the A3 Delta. The hard body armor, previously shot with 9mm and 223 rounds, demonstrated significant resistance to stabbing attempts. The TEO Hum V only penetrated about a quarter of an inch, while the A3 Delta went deeper but did not achieve a full pass-through. The findings suggest hard body armor offers superior protection against knife attacks compared to soft armor.
This video tests German Level 1 body armor against various ballistic threats, comparing its performance to American NIJ standards. The armor demonstrated effective stab resistance and stopped .22 subsonic, .45 ACP, and 115-grain 9mm rounds. However, it was penetrated by 300 Blackout subsonic rounds. The presenter concludes the armor is likely equivalent to a US Level II or Level IIIA plate, offering good value for pistol and shotgun threats.
