Is it possible for a human to cut a bullet in half?
Watch Isao Machii, who holds several Guinness World Records, accurately use his samurai sword with lightning speed to cut a bullet in half. Cutting a speeding bullet in half may be a trick shown in Rajnikanth movies but it can actually be done in real life by a real ninja.
A bullet is made from a soft metal (lead) while a sword is most often forged from steel. Steel will hold its integral shape much longer than lead. So in answer to your question, yes a sword can split a bullet.
Can a katana deflect bullets? - Quora. Theoretically, yes. It depends on a number of variables, but any sword or blade could theoretically deflect a bullet. Whether or not the impact of the bullet would deform or break the blade is a different matter.
No. Bullet and/or blade may shatter, but it won't be cut.
This myth has been carried over from a story about a Damascus blade owned by Saladin. A katana can chop a regular sword in half. Fact: Any steel sword can break if it's struck at the wrong angle. Chopping one in half, however, is highly unlikely.
Before engaging an enemy, a samurai would recite his name, ancestry and deeds of heroism. Upon defeating an opponent, he might compliment him on his bravery before decapitating him.
The sword wins, cutting the bullet in two. And with no dents, scratches or nicks in the blade. Of course, the soft slug is hitting hard steel edge-on, but nonetheless it's nice to see some movie science that is actually true for a change.
Yes, provided the cut is done with proper technique. Pretty much any cut centric sword can. It can also glance off as the skull is rather deflective, but connect properly and yes, it can.
Each one is unique with its own defining characteristics. The longsword is a longer, heavier sword with more stopping power, while the katana is a shorter, lighter sword with a stronger cutting edge.
In most cases, the sword may be destroyed and will shatter into tiny pieces, and this may injure you and those around you. Some others claim that the sword may successfully break off parts of the rock but could never cut through. Modern technology hasn't been able to make a breakthrough in this aspect.
Can a katana go through bone?
A Katana can cut through bone if it's either very sharp or very heavy. If it's heavy, it doesn't so much cut as smash it's a way through bone; the force and mass involved overcome the ability of the bone to absorb impact and it breaks. A katana can cut off the arm (or head) of an opponent.
Bullets easily puncture most walls, doors, and floors. However, brick, concrete, and cinder blocks effectively stop most common calibers.

No. A gun barrel is basically a thick steel pipe. A sword will scratch it, but will definitely not cut through. If the gun was made of low-quality steel and you were fairly strong, you might bend the barrel slightly or damage some other part of the gun from the shock.
yes you could but it would not be good at it and you would destroy it. No sord are good for wood shopping and the katna is one of the worst. if it is a real historically made one with a hard edge and soft spine it lack the ability to flex so it would probably bend as soon you hit a solid piece of wood hard.
Can you really curve a bullet when shooting a gun? No. This is an entirely fictional concept. Any effect the barrel has on the bullet is complete once it leaves the barrel.
However, when such projectiles hit bone, they may fragment into multiple smaller pieces that are often retained near the fracture site (Fig. 1). It has been our observation that fractures with a substantial amount of retained bullet fragments near the fracture site are at risk for delayed or nonunion.
Tissue in every one of these organs was damaged. Blood was leaking into his chest. When bullets enter a human body, they don't just pierce tissue, they shatter bones and dislocate limbs.
The bullet cannot deviate its path to such an extent that it makes an 'S' curve around an object. In fact, the bullet would be moving so swiftly that the effect is negligible. It is so negligible, in fact, that the strongest force amongst all those acting on the bullet is still gravity!
