Tbh, I kinda wanna watch the video of the samurai sword spreading butter.
pretty sure it will break
+Nathan Bodet You can't break butter.
Golden Duck butter will break katana
Golden Duck
KoyasuNoBara it's out there
I lost it when penn said a non japanese japanese swordsman hahahahhaa
+Nth Degree Thing is, a weeaboo wouldn't actually know how to do it. It papa Franku has taught me correctly of course.
***** Oh right!
***** Oh shit!
+RealLifeJabbaWocKeeZ preeeeetty sure that's adrien brody.
+PuertoRicanSpaceSloth NYIEEEEEZZZZHHH ! EYY B0SS !
Penn's sarcastic remarks are what make this 100 times better than any other mythbusters-style video. It's like he can't help but point out the tropes, the bullshit and fake enhancements these videos always have for dramatic effect.
...Also I like to think that Teller is always beside him in the recording booth.
What is this? Penn & Teller or Mythbusters?
A great combination of both
Penn & Teller tell a lie, it's a fun show
Nah, this doesn't have 40 minutes of fluff and recap
Penn and teller should be mythbusters.
fedos nah they dont blow stuff up
It's because of the red handle. Should have gone with Yellow.
+Jason Summer that red lever, yellow lever joke was so obscure but still pretty funny
+jetnut89 I didnt get the joke
+anonymous fapper
An old tongue-twister that actors use to loosen up and avoid slipping up on stage is saying "red leather yellow leather" several times without messing up.
He just swapped out "leather" for "lever" :)
Try it! red leather, yellow leather, red leather yellow leather redleatheryellowleather....
@@Nu_Gundam78 The tongue twister!!!
@@Nu_Gundam78 and you know penn has used it for years to loosen up his over used tongue. Lol
"Listen to that amazing...fake sound effect!"
my favorite part of the video! Hahahahaha
hehe
I was saying the video was so much better with Penn commentating.
+Iyana your comment made it to the title of a post on 9gag tv
+abrox What does that mean? Haha
I was here to see penn and teller do a magic trick but ended up watching the entire myth busters episode
same
"We got the same weapons expert we didn't introduce earlier..." Classic!
The guy saying I'm fucking amazed made the whole video twice as funny
Did the butterknife just fool them?
i guess so hahaha
😂😂😂😂😂😂😂😂😂😂😂
Why doesn't this have more likes???
Should be top comment 🤣
"The presentation was great but I think another word we could use to describe it is as a *SHARP* presentation maybe?"
Butter knife: "Nope, nothing sharp"
"well if its not sharp then it must be slick because you FOOLED US" loud noises
lead is soft, steel is hard
+lukassnakeman On top of that, the angle with which the bullet impacts the knife makes quite a difference. Going through it would mean going through one inch of steel, but since there's nothing on each side the mass, under those circumstances, tends to split and go through the path of least resistance.
+lukassnakeman Iron, not lead.
+Sarcastic Marauder bullets are usually lead.
thesourceofx Yes, but refer to the original post wasn't talking about bullets
+Sarcastic Marauder ...It probably was. You know, bullet vs knife. Lead vs steel.
Anyone else think this is like a mythbusters but with penn and teller
Foohey yep
Foohey Now I want to see Penn and Teller vs Jamie and Adam
Foohey And like mythbusters, this show probably started out cool (dunno, never watched the early seasons), but degraded into proving stupid obvious stuffs.
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.
+Foohey I prefer to think Mythbusters is like this just without Penn and Teller
+๖ۣۜ♥๖̶tacokitten๖̶ Lets tell that to ERB
I can always count on Penn to say what no other tv personality will. Finally someone pointed out those hokey, fake sound effects shows put into their slow motion replays.
I was actually about to get annoyed by the sound effects but then he acknowledged it and it became funny instead
“And here is a butter knife that we stole from a local diner” lol
"tell us non-japanese, japanese swordsmaster!"
we need butter knife in csgo
April 1st maybe
1st reply 😂😂
+E X E R and it should be able to slice incoming bullets!
MrEpic Pat Definetely! And this Butter Knife should not be Covert Knife, but a Contraband Knife that worth $590.45 in the market.
+E X E R if you shoot at it and he has it has his butter knife out it doesnt no damage.
i wanna see a cgi action movie scene where a guy splits a bullet w a butter knife
Would prolly be a Remo Williams movie, if anything
I must be Jackie Chan.
Sounds like something that would be in a Dead-pool movie, Dead-pool doesn't have his sword so he splits a bullet to prevent the harm of his lover.
Sounds like John Wick

easy on the butter, holy SHIT
+TheMausymaus did they put butter on cake? wtf?
+Christian leontsinis muffin i'm pretty sure

sounds good to me
mahindra harold vietname
SysGhost It would actually be bad ass to see a kung fu or samurai scene where the guy improvises in a fight in a diner or fancy restaurant using butter knives to deflect incoming bullets from bad guys.
That needs to be a thing! That would be a hilarious martial arts comedy
Why the fuck was he putting butter on a blueberry muffin
Murica.
Because it's fucking delicious!
+datonz no it's diabetes and a muffin is similar to a cake, why the actual fuck do you need butter on it.
The scroll, the scroll, the button, the button, the scroll is so smooth lika butter on a muffin!
Because that would be hillarious.
Penn and Teller: "Amazing!"
Forged in Fire: "We've got some chipping there.. " 😂😂
This knife... will spread.
"Im fucking amazed man, but im not gonna say it". Best reaction
It would have been great if they'd taken a minute to chat with a materials scientist, an engineer or a physicist about *why* both blades split a bullet.
unclvinny Both are made of steel. The bullet is made of lead. Lead is far weaker than steel and is easily molded/split.
+unclvinny They probably do that at the end of the show.
The way the show is build is that they have 5 stories that they talk about and one of them is fake. They let people vote which one is fake and reveal the actual fake at the end and explaining why the others are real in the progress. I think. Not sure.
What kind of butter knife was that? The butter knives i use have those tiny teeth like edges that could probably cut through flesh if tried hard enough.
+James Hald Teeth dont CUT things, they, well, mangle if they have enough force behind them, the thing here is that the bullet is moving at a very fast speed and the static knife has a very small point of impact, which means that all of the preassure will be in that exact spot, leading to the bullet seemingly being split.
+James Hald A lot of the things we refer to as butter knives aren't actually butter knives. Butter knives are those funny little paddle ones that aren't even sharp. The ones you're talking about, I think, are the same kind most people get when they buy a box of silverware. And those are actually dinner knives.
visual.merriam-webster.com/images/food-kitchen/kitchen/silverware/examples-knives.jpg
+ExplosiveBG Funnily enough, that's exactly what a sharp blade does. It has microscopic jagged edges that do the same thing a hacksaw would.
the butterknifes I use are made of plastic and are quite big. It is much easier to spread than with the ones in the video... just look how gross those scones look
those butter knives can definitely cut through flesh. I had a friend go to hospital because he grabbed the seemingly safe 'edge' and someone pulled the knife.
you can actually hear where the ads are supposed to go
ikr
Bullets are made with really soft metal, because they're supposed to expand in the barrel to facilitate the rifleing. Add that together with the speed of proportion, and just about anything solid and thin could cut one.
They need to be relatively soft on the outside to squeeze into the rifling, but their inside can be very hard. They looked like a single piece of lead in this case, though.
"Tell us! non-japanese japanese sword master"
lol it's the little things in life that make me smile.
it's LEAD!!!!!!!!!!!!!!!!!!!!!! I'd like to see this test again with full metal jackets
Then the test would be ludicrous because common bullets are made from lead
mitchell fowler
what ISN'T ludicrous about the test they actually did? anyway, as it stands it only shows how much softer lead is than the metals used in knives and katanas which actually shows nothing and is unimpressive. I believe a katana could split a copper plated bullet and that's what I'd like to see.
KevinJC1991 I will agree that splitting a bullet in half with a sword or knife is stupid, but using lead bullets makes alot more sense still
KevinJC1991 Considering the test is equal...that doesn't matter. Not to mention...did you think that copper is harder than steel?
***** would it smash a katana blade? i think so. The fact is that this test is putting soft metal at a high speed against a hard, stationary target. it means nothing and yes, i know that it is lead wrapped in copper, thanks for the copy/paste from the dictionary. what is your point?
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.
at least one who knows his bussines.
lets not forget traditional made katanas were a one gig only thing in a fight for the metal in japan back in the day was of rather poor quality which even after folding and correct quenching was rather prone to bend.
actually because of this background knowledge i actually thought the blade would get a bigger dent after being hit by a bullet.
They need to do their own show, in this format. It would be amazing. The humor is great!!!
Where do you think this is from?
Penn's narration is the best.
Bill stating, “I’m fucking amazed” had me rolling😂
"And here's a butter knife we stole from a diner"
That killed me hahahaha
"And listen to that fake soundeffect!" haha love it.
tbh, the butter knife more of *broke* the bullet in half than cut it, and the knife got all scratched up whereas the sword was unscathed. Still, it's a good demonstration that bullet-splitting isn't what makes a sword badass.
You... you guys know that this video is a joke, right? It's fake...
*Unsheathes butterknife*
More entertaining version of Mythbusters?
Nah. They don't have Kari.
MUCH LESS ENTERTAINING
The sharpness of the sword is almost incidental. The material is what really matters. The butter knife was steel. Lead vs Steel will always work out this way. It's basic material science.
Then explain how I can cut down a tree with a mushroom in minecraft
supersonic physics does tend to behave weird
@mandellorian Don't be mean though, be nice.
Well, mostly. Both are thin enough that the point of impact is such that the bullet stands no chance. The sharpness of the sword allows it an even finer point of impact, thus cleaner cut though.
stainless steel is much harder than lead so no surprise
If only mythbusters was still a thing. I would LOVE to see a collaboration between PT and MB. Just imagine the hilarity that would ensue between those 7.

“Weapons specialist” while he sweeps everyone and loads the firearm with his finger on the trigger...
To be fair, he is American. The idea of muzzle awareness and trigger discipline may as well be a running joke
It's because he's a police officer
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.
@@tjfrye11 Most of your citizens think you're legally allowed to murder someone for trespassing on your property.
Vanessa Magick whether or not you are is based on state laws. In some, you can be convicted even if they posed a threat, in some, you can shoot them if they breathe on your grass. It's not a nationwide law, because different states have different crime rates.
Why would anyone be amazed that steel is stronger than lead?? The knife just needs to be soft enough that it's not going to shatter from the impact, and cheap cutlery fits that bill... unless I'm missing something?
People have very high expectations of bullets and guns. I'm sure people were thinking that because of the velocity, it would just mess up the butter knife.
it has more to due with surface area than just general hardness. turn either blade to the flat side that that bullet is going right through it.
@@dinozorman If you turn it on edge, the cross-sectional thickness is something like 15x less than if hitting it on edge. It's like trying to shoot through a piece of paper vs a book.... I small book, but I think you get the point.
It's so weird to see him so skinny now
hiv/aids does that... rip teller!
sorry that you too have hiv/aids, but don't be mean to strangers online. i curse you!

Can a butterknife split a katana? Or can a katana split a butterknife?
Dibs on the katana.
+donbasuradenuevo How can steel split steel?
+Hyper Ask Zorro, he will explain it 😝
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.
donbasuradenuevo I think that modern butter knife is made of better steel than old pig iron katanas.
Hyper
No. Modern butter knives are made from stainless steel that has not been tempered for a hard edge so it is easier to produce. Katanas were never made from old pig iron. They were made from carbon steel. And retempered for durability and combat.
I love the sarcasm and the sound effects in this video.
well, my life is at last complete. I can now die a happy person, complete and fulfilled, knowing that a butter knife can indeed split a bullet. Thank you Penn!!
Samurai sword: I can cut a bullet in half
Butter knife: Hold my beer
Adam Savage & Jaime Hyneman do a magic trick: They look like Penn & Teller!
I read the title like 3 times and i kept reading, "Spitting bullets with butter knives" and i was really confused until i was about 90% done with the video...
I would love to have Penn narrate my life.
Well, there's splitting and then there's shattering, plus you'd want to consider the damage done to the knife, which seemed quite deflected.
In the end, bullets are made to penetrate flesh, bone, organs, cloth and sometimes armour, not stay in one piece.
Never put butter on a blueberry muffin again. Please.
You are missing out my man. Especially if it's European butter.
Well it makes sense.
What we saw her was a transformation of moving energy also called kinetic energy into another type of energy.
Because of the setup. 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.

Shitty steel is still harder than lead. Of course the bullet loses.
balzonurchin it may have won if that bullet was a full metal jacket (FMJ) or a total metal jacket (TMJ).
This is amazing when you know nothing about the Mohs hardness scale.
quartz is harder than steel. Try shooting at a piece of quartz. It's more than mere hardness.
@@khornetto "More than mere hardness" is what my girlfriend likes to say.
@@khornetto it's likely also the speed of the bullet impacting the blades edge on. The relatively softer lead hitting the harder steel, means the easiest way for the mass to continue moving forward is to be split to either side. I think if you shot the flat of the sword or butter knife you may get a different result.
@@DamienTB yeah she loves girth too, doesn't she
@@CrashB111 exactly, all these people talking about "well duh steel is harder", dont understand momentum and surface area lol.
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.
It’s kinda funny, the folding part of making a samurai sword making it better is sort of a misconception.
You only need to fold out impurities... in lower quality steel. 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.
I must watch the videos of them trying to spread butter with a samurai sword.
It's not about the size of the sword, it's about how you use it.
- Obama Ghandi 2012
Who doesnt love a good blueberry pancake with 1 and half pounds of butter in the morning? 1:06
Hmm. Based on the small spread of the bullet halves from the samurai sword, you would probably still be hit by the bullets, but the butter knife spread the bullets much farther apart! It’s probably actually a better choice when you bring a knife to a gun fight and you’re out of knife range, because you can actually split the bullets and live!
anyone standing behind the butter knife will now have 2 new holes
Lol
wanmohd danial And behind that man 4 holes. And then to INFINITY AND BEYOND.
Stevon Robb How high were you when you wrote this?
"Weapons expert" has his finger in the trigger guard. Also, using non jacketed ammo, most steel should be able to split a piece of lead like that
that's why they used it. you can't shoot an edge with a regular bullet without at least leaving a mark, curling or chipping the edge in some way.
Please bring this show back it was so good
Can he please just say “This type of sword is called a Katana, which was used by Samurai” I’m tired of him saying “samurai sword” every second

Relatively speaking, you have to imagine the experiment going in the other direction, as both are equivalent events.
What if a butter knife was swung at the speed of a bullet, and hit a bullet that was not moving? Posing the question this way, it's a lot more obvious as to what the outcome would be.
Is a butterknife just as dangerous as a samurai sword?

Note to self if someone pulls a gun on you whip out a trusty butter knife haha
it shattered the bullet .. not split the bullet XD
well the katana split the bullet, but the knife shattered it. Not the same
+Sinisa Jovanovic It's because the katana has a sharper edge that doesn't change the outcome
Yes it does. It's like if you take a knife and slice an apple in two and take a hammer and “slice” the apple in 50 pieces.
+Sinisa Jovanovic well, if you want to call it "shatter" it shattered it into two pieces. Just like the katana, but with a different word.
That was not 2 pieces, it wasn`t a clean cut at all
Sinisa Jovanovic
The question isn't of manner of breaking but of strength. The butter knife passed and it was slightly bend probably caused by the knock off of the bullet, which might have caused the bullet to break down in a few pieces. If you watch closely the bullet breaks in two and then fractures.
I enjoyed sharing this video with my Materials Science class today at Teller's alma mater, Central High in Philadelphia. Good science, good humor. You guys rock!
224!
Has to do with surface area. The butter knife has a smaller area in the thinnest part of it, the edge, than the tip of the bullet. The sword has an even smaller one, which is why it gave a cleaner cut.
they do not know how to spread butter
FOLDED 1000000 TIMES BUTTERKNIFE, NIPPON GO HOME
Didn’t think penn and teller would be the new hosts of myth busters
Well they don't entirely understand how katanas are made, but they have a firm understanding of physics.
swords were made the same way Hundreds of years before the creation of the katana in medevil Europe and were arguably better. it truely annoys me when people preach the infalability of the katana.
Just cause I have nothing to do with my life I went ahead and looked up your little factoid. Upon further research regarding the technique of making medieval swords and that of Katanas I realized they were the same, you know demascus (
Katanas weren't made of high quality metal. The smithing processes they used were used specifically because japan had really low quality steel to work with. Folding the metal again and again helped more evenly distribute the impurities, and helped remove impurities with each fold.
rep304
Wrong on so many levels... the Katana was not made from 'high quality metal'. As a matter of fact, it's the other way around. The metal they used was incredibly bad. 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.
thats a lot of butter to put on a scone
Those bullets are just made of cake
I really came back to this video in 2020 just to make that joke wow
It's probably simple physics. Because the bullet is moving, and the butter knife is fixed, the mass of the bullet wants to keep moving, the only way it can do that with the knife in the way is to split. The metal that the bullet is made from (brass) is thinner and softer than the stainless steel the butter knife is made from. Also, the butter knife is hard and inflexible, which is why it sustained damage during the collision, and the samurai sword is flexible and able to accept the force without damage. But there is another force in play here too... The molecules in the moving bullet vibrate and that harmonic effectively makes the brass more pliable. That's probably why bullets usually crumple on impact with something hard instead of just rebounding off.
why did the guy in the educational film remind me of hitler
I was browsing the comments just to see if it wasn't just me.
Yes the butter knife will survive. It is stainless steel. I question the edge though. It may need sharpening. What the non Japanese samurai sword master was saying is correct. It is also just steel but was folded a lot to turn it into steel.
Yep am not amazed that much but without sharpening it still did the trick. Guess forged in fire needs to come up with a new test then...
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.
I LOVE that he mentioned the fake sound effect 😂
Imagine being a hitman shooting at your target and getting your bullet split in half by a butter knife 😂
3:50 ok, boomer
the katana was an extremely mediocre blade infact. for one it was believe it or not quite a fat blade, probably due to the fact that it was an incredibly easy sword to make and was made by the worst of smiths.
the steel folding is true, and it did work, as shown by the celts who did it almost 2 millenia earlier.
+the stalking "biscuit but but.. anime taught me that katakana are the best swords and have supernatural powers :'O" - majority of katanas fans over the internet.
Really, European swords are far superior.
Ruben Fernandes
nah animes are just 10Kg monsters with unecessary spikes and curves everywhere xD
+the stalking biscuit xD
+Ruben Fernandes hahaha katakana?
Well they didn't fold it "1000x times" they folded it maybe 10 times and because of math if you fold something over you get two then you do it again you get four then again eight, etc...
If you were to fold it 1000x imagine the hunk of metal you're starting out with and imagine how heavy that'd be translated into a sword.
"We got the same weapon specialist we did not introduced earlier to shoot the butter knife" lol
This video gets recommended to me atleast 2 times a year. Maybe even more. But every time I watch it like I’ve never seen this before.
Holy shit, this is inaccurate. Katanas weren't made of steel, they're not made of two metals of any kind, and they're not folded "thousands" of times. Also, they could only stay sharp to cut through three or four tatami mats perfectly.
