Splitting Bullets with Butter Knives: Penn & Teller Tell a Lie

Ғылым және технология

What this video proved is that lead is weaker/softer than steel. Something that's already a common knowledge. Don't really need a butter knife. Just use a similar thickness steel plate, position it the same way (thin side facing the gun), and it will give pretty much the same effect.

    The way they showed making the katana is the modern method popularized in ww2 for faster production. The traditional method uses only one kind of steel folded many times to remove impurities then hardened in a way so the back of the blade (the spine) is softer than the edge allowing for it not to shatter.

    Wow the 2 comments above me r wrong... A lot of Americans do legally own guns, but every legal gun owner that's actually going to brag about it knows proper gun safety & practices it 24/7 in fear of being mocked by comments like this 1 showing they don't know wats going on... To become a police officer, u then have to have more gun training as well as training in other firearms not available on the market, etc... Basically, the idea that Americans or cops are stupid wen it comes to gun safety is stupid. Most gun deaths in America r by suicide. Most gun crime is committed with illegally obtained guns. Don't make stupid generalized comments with no basis to them.

    Hyper Steel varies between steels. Take, for example, alloys. There are a LOT of different steel alloys. For starters, the most basic steel is a mixture of Iron (Fe) and a very small amount of Carbon (C). You can get different properties (hardness, ductility) by varying the carbon content. Now, you can even add more elements such as Chromium to make it stainless steel. One can add a lot more different elements and get a lot more properties. Next, comes the heat treatment. A respectable katana is forged using a heat treatment that gives different properties along the cross section of the blade. You want hardness to keep a good edge, and toughness (ability to absorb impact) in the inside. Butterknives almost never get a complex alloy or heat treatment because of cost. Only crazy rich people would invest lots of money on a butterknife, so they are made incredibly cheap. That means cheap steel alloy and cheap heat treatments, thus making it more prone to break. Lastly, mass. A katana or any sword pretty much has an enormous mass compared to cutlery, thus having more impact energy. Thus, a butterknife will be able to absorb less energy than a sword when impacted.

So some medieval European swords, for example, didn’t need to be folded nearly as many times because they had better steel, and such is absolutely the case with modern assembly line steel used in the butter knife.

The bullet is forcefully stopped by the knife. And the energy tries to find a way to escape. And the only way to do that is by breaking the bullet as it is made out of softer material then the knife. The sharpness doesn't matter.

  • @galactor123
    @galactor1234 жыл бұрын

    More than a few people have pretty much said it, but just to reiterate, it has more to do with both the round chosen, as well as simple material science. .45 ACP bullets are not meant to be armor piercing. They aren't even supersonic. They're meant for maximum power against a soft target, and thus they are made soft so that they expand in the wound and cause as much damage in the wound canal as possible. It's morbid, but thats how a soft point or especially hollow point round works, it's meant to spread out and slow down once it hits a target and therefore is built fragile and soft. With that in mind, a fragile soft metal, striking a hard forged metal is going to break. You don't need sharpness in the blade, because unlike when the sword sliced through a fish, the sword is not sending it's force into the object, but is having an object with an insane amount of force suddenly stop on it. Therefore the bullet acts in much the same way as if it had just struck a human body and chips, fragments, and generally breaks apart as much as possible as it was designed to do. If you fired a steel point rifle round at that sword? I think the results would be very different. At that point the strength of the steel would come more into play.

The reason why the metal they use, is folded so many times, is to get rid of all the impurities there was in the steel. Conversely, the European blades had no impurities (or so few that there was no need to get rid of them), so they didn't have to fold the metal.

    Sharpening not needed, if you notice the butter knife bullet more of shattered compared to the sword cut the slug. It is a lead slug (very soft relatively speaking compared to other metals) moving at high velocity hitting stationary piece of thinnish steel which is much, much harder. The stainless steel of the butter knife most likely has a surface hardness very close to the sword, just the sword has more toughness (it is a metallurgy thing). Use a steel or brass slug and results will be different.
