ninja VS. bulletproof vest..?

Swordsman, every time. Even if they were forced to attack the vest, the Katana can literally cut somebody from head to groin in an instant, with a bullet-proof vest you would still die.

One, Swordsmanship is NOT ONLY their thing, They also train in Jujustu, The way of the spear, the way of the Bow, and horsemanship.

Two, The Ninja or Samurai could easily strike for the neck in this situation.

The Roma Plastilena Clay Vest may withstand a stab from a Skilled Swordsman, Then Again. The Swordsman wouldn't strike at the armor. Not all vest are designed to withstand Stabbing eg. Silicon Gel Vests or Gelatin Vests. If these were the vests, The sword would easily Penetrate.

I actually have under no circumstances considered a attempt like that executed. I actually have considered a espresso can finished of sand supply up a .30-30 win bullet lifeless without penatraiting the option aspect even as an arrow fired from a recurve bow pentraited with the aid of and through. Having seeing the bullet vs arrow demo i'd say its authentic. Its no longer the speed notwithstanding the realm of contact if I keep in mind suitable.

The sword would penetrate, as a vest is designed to stop a bullet, not a blade. Bullets are generally made with lead and are dull tipped, blades (especially high quality blades) are forged of much harder metal and are much sharper.

a ninja, does not fighr in combats facingthe opponet mostly, nd a samurai chooses to take him down first

is the vest also a turtle neck?
