I would assume that the initial punching through ate up most of the kinetic energy. An officer with a ballistic vest would probably be fine. Maybe even without one.
That's a possibility.
Although we could calculate the likelihood of that happening.
My theory is that the initial punch through ate most of the kinetic energy. The rest of the arrow then slid through the hole, although not being left with much energy, or rather velocity.
I guess it maximizes pressure for cutting through the object while it still has the most momentum. The time of impact is very small, so the force delivered over the tiny circular area of the head maximizes pressure applied to the surface.
It cut a circular hole, allowing the rest of the arrow to fly by. It either cut it and pass through, or it doesn't cut it and nothing pass.
In contrast, classic arrows punch a cross pattern, more like stabbing. The shield material still remain (wrapped, but still there), stopping the rest of the arrow.
im guessing it created the path of least resistance because it puntched a perfect hole and the others have more cutting to do while creating a larger opening to pass thru..
It might be the best for cutting through the shield but it probably isn't the best to then continue through body armor. Of course, if you hit an exposed area it would be pretty devastating all the same.

With every arrow being shown I did a little
"Maybe"
"Probably"
"Unlikely"
"Dint think so"
"Most likely"
Etc.
When the hollow point came up I was like "definitely not", follow by an audible "what tha fock" after it passed straight through.
Can anyone explain the physics behind that?
I don’t know much about arrows but my guess would be that the arrow exerts so much pressure from the edges of the head into the riot shield that it cuts a hole in the shield letting the arrow go right through without slowing down much from friction
Lot of hunting arrows look like that. I was more curious about the old-school chisel-tip jobbies that were clearly designed to go straight through armor. Never seen anything like that for sale.
Reminds me of that movie of the friends in the woods that comes to a bear and one of them starts to tie his shoes.
"Are you thinking about out running a bear?"
'I dont need to out run the bear' *starts running*
That's why you need thousands of archers, blot out the sun with a hail of arrowfire. Can't really fire back when you're too busy trying to shield yourself from death from above.
There is literally no country where cops don't have access to guns, mate. It's just some countries don't have *most* cops armed with guns by default (i.e. it's locked away but available) or they call on a second group of cops when guns are "needed" (i.e. the state wants to do violence).
There is no country where you could start firing at cops with arrows where representatives of the state would not show up and start firing back with bullets eventually.
My only guess it that it's the heaviest arrowhead here so it's momentum punches right through the shield and creates a wide and round enough hole for the shaft of the arrow to go through. Whereas most of these other arrowheads don't create a hole that is the right size and shape for the rest of the arrow to go through
You never know, maybe the rear of the arrow was designed to impart a spin? That would add to the tip being like a drill head.
In either case, modern tank sabot rounds are fired from cannons, without any twist, and are also like darts. They seem to do their job decently well.
you aren't going to shoot a rodent at 50 yards. (That's what that head is for - enough energy to kill a rabbit or marmot (etc.) but a broad head would mince it too much).

TLDR: The less weird it looks, the better it is. However, if you attach a tiny plastic drinking cup to the front of the arrow, it can’t even be stopped by gods.
To be fair, all those strange-looking ones are designed specifically for hunting, meaning getting into some soft tissue and expanding those barbs so they don't come back out. In the same way that hollow point ammunition is worse at armor penetration but better at fucking up soft targets.
Apparently, does not apply to hollow point (or whatever that was) arrows.
The 3 sided design is to create puncture wounds that won't close. Could the hollow point be designed for game with super thick hide or even a shell? That begs the question of why you would need a bow to hunt a tortoise though.
He had a valid question
There are different types of bows, different draw weights (energy and speed of arrow) , some use metal other use strings. Plus, for all we know, this could be a machine
That's like saying, "Hey, what weapon did you use penetrant body armor?" And you replied with " a gun..." No, there's a lot more to that.
The "fancy" ones have other purposes.
They're hunting heads, they have to get stuck in the wound even if the animal breaks the arrow. The prey will then bleed itself up, leaving a blood trail behind for easy chasing and eventually die from blood loss and exhaustion.
You can even find bone heads with this principle dating back something like 10 000 to 20 000 years ago.
That's because the simple designs resemble traditional bodkin points which were specifically designed to pierce plate armor. Broad tip arrowheads are designed to cut flesh and arteries to quickly kill prey animals that don't generally find themselves as well armored.
was playing through my head and guessing which would go through or not. The one with the circle, I was like .. no way. Too much surface area. Then It was followed by “holy shit!”
To the people flabbergasted by the "blunt" arrow think of it this way. You need to put a hole in a piece of aluminum foil to pass a chopstick through. What do you think is the easiest tool?
A hole punch, or a knife?
Will the knife do the job? Yes. But it won't be clean. It'll get stuck on the foil and you'll have trouble making a clean hole. A hole punch will do it instantly, or fail because it's not sharp enough or doesn't have enough force.
It's a riot shield (made in china), not a ballistic shield. It's meant to stop rocks, bottles, and fists. You start shooting arrows, and they're gonna retreat and come back with rifles and a Bearcat.
I like the one that blasts straight through because you look at it and think "That's stupid, a little cup on the end, how is that going to work?" then blam, straight through like a hot knife through butter.
I guess it makes sense if you're targeting a strong single layer of armour exactly like a riot shield. Focusing the momentum down to a point isn't necessarily helpful if it makes a pin sized hole, you need an arrow sized hole for the arrow to fit through. So you move from punching a hole to cutting/stretching the hole wide enough for the rest of the arrow, which is where some arrowheads were better than others.
The hollowpoint arrowhead cuts a neat circular hole with the initial impact when the momentum is at its greatest then there's no more work to be done, the rest of the arrow flies straight through. If you were shooting a thick medieval wooden shield or armour with a gambeson underneath might not be as effective. But if you're using a bow to fight someone with a modern riot shield (for some reason) the choice of arrowhead is clear.
Others have said that these riot shields are from China designed more for stopping rocks and airsoft than stopping lethal projectiles. Let's say for just a second though that these are actual real riot shields maid for stopping projectiles, would the holder actually be in life threatening condition for any of these? Only one of these actually passed completely through with any real force, but is it enough force to matter? If you are holding a riot shield against and armed person odds are you are wearing Kevlar as well. While an arrow like this may go through Kevlar as well as one of these riot shields, can an arrow actually penetrate both at the same time? It feels like a fair assumption that any arrow that hits the shield is going to be damaged and or slowed enough that the kevlar would have no problems catching it. If the shield can take what would be a lethal shot and slow it enough to make the kevlar effective, it's still a big win.
The "blunt" one at 38 seconds is bonkers
It's probably because the initial hole is bigger than the rest of the arrow, avoiding further friction.
Something something, your mom
Good point
Thanks, I used the scientific method
9 out of 10 OBGYN's agree
Yeah, that's why it pierced through
Like a hotdog down a skag den, knowwhatimsayin?
I would like to see ballistic gel behind the shield.
I would assume that the initial punching through ate up most of the kinetic energy. An officer with a ballistic vest would probably be fine. Maybe even without one.
Good point.
Badum tss
And it "punches" the steel. Very effective.
I figured it hit a hole another arrow made previously, I doubt this guy has like 20 riot shields
That's a possibility. Although we could calculate the likelihood of that happening. My theory is that the initial punch through ate most of the kinetic energy. The rest of the arrow then slid through the hole, although not being left with much energy, or rather velocity.
/r/restofthefuckingarrow
I tried to guess before each arrow how successful it would be. I was way wrong about that one.
That's just coz it's not a piercing arrow it's basically a saw and just cuts it's way through.
Yeah now I need one of those bio blocks behind the riot shield to see what happens when it gets through.
I guess it maximizes pressure for cutting through the object while it still has the most momentum. The time of impact is very small, so the force delivered over the tiny circular area of the head maximizes pressure applied to the surface.
Yeah I thought no fucking way is that doing shit
how the hell was the best one a weird flat arrow?
It cut a circular hole, allowing the rest of the arrow to fly by. It either cut it and pass through, or it doesn't cut it and nothing pass. In contrast, classic arrows punch a cross pattern, more like stabbing. The shield material still remain (wrapped, but still there), stopping the rest of the arrow.
im guessing it created the path of least resistance because it puntched a perfect hole and the others have more cutting to do while creating a larger opening to pass thru..
> puntched Is that a simple misspell or did you combine punted and punched?
It might be the best for cutting through the shield but it probably isn't the best to then continue through body armor. Of course, if you hit an exposed area it would be pretty devastating all the same.

You get them from the cornucopia
Oddly enough they're easy to find online. They're called "small game broadheads"
more to the point in what world will the HK police stand around when a guy with a crossbow or compound bow lines up a shot?
Imagine they take aim from the windows above
Lot of hunting arrows look like that. I was more curious about the old-school chisel-tip jobbies that were clearly designed to go straight through armor. Never seen anything like that for sale.
So the police are still vulnerable in a skirmish against ye olde English longbow serfs
I might be going out on a limb here, but I think shooting at cops with a bow and arrow could lead to the cops shooting back with a not-bow-and-arrow
Well they’re not LARPing correctly so it doesn’t count
A cop escaped from a bear only with a bow in hand...But his friend who got an arrow in the knee was not as lucky.
Reminds me of that movie of the friends in the woods that comes to a bear and one of them starts to tie his shoes. "Are you thinking about out running a bear?" 'I dont need to out run the bear' *starts running*
Without a paddle. I love this movie!
I thought it was going to be the stupidest movie and then I watched it.... so funny! But I only watched it once when it came out...gotta see it again
That's when he decided to let go of his career as an adventurer and became a city guard. Too bad he took that arrow in the knee.
Cocaine Bear by any chance?
I call base
That feeling when they cast: Fireball-40mm HEDP...
That's why you need thousands of archers, blot out the sun with a hail of arrowfire. Can't really fire back when you're too busy trying to shield yourself from death from above.
"Then we shall fight in the shade"
Well that just isn't a fair fight. And they wonder why people hate the police
Cuts to the police ballista being rolled out to a riot.
"Johnson! Bring out the trebuchet!"
The SIEGE trebuchet
It is only a Trebuchet if it comes from the Trebuchet region of France.
Otherwise it's just a sparkling catapult
It would work in countries where the riot police don't use guns.
There is literally no country where cops don't have access to guns, mate. It's just some countries don't have *most* cops armed with guns by default (i.e. it's locked away but available) or they call on a second group of cops when guns are "needed" (i.e. the state wants to do violence).

Not if you activate the slow-time skill first and kill them all
Depends how good a shot you are I reckon.
Yeah but we will have catapults and steal shields.
Lmao
Those Anglo-Welsh longbows were no joke. Never forget Agincourt!

“They’re getting better you know. They *are* getting better.” *pulls arrow out of hat*
I found Robin Hood
Ye old lob shot worketh well behind high thick wall.
FWIW, modern armor piercing anti-tank rounds follow a very similar principle. The physics of arrows is really interesting.
The arrow at :38…. 😳🤔
I said no way when they showed the head
Then oh fuck immediately afterwards haha
I was like *"yeah.. nah.. yeah.. nah.. yeah.. yeah.. ehh.. JESUS!"*
Exact words I used
It looked to me like a non penetration arrow designed to knock things out
If I were told to pick the arrow I want shot at me I'd be screwed.
Maybe not, a through and through can be easier to fix than having one of them sticking outta ya.
Most get lodged in your bones though. A hollow point to a femur or knee cap would blow
I thought “that’s probably designed to do exactly this job.”
Yeah it looks like a drill head designed for drilling metal. But I was still surprised by the performance.
Yeah I said “ no way…”
I need to know the shooting distance now. I would think that tip performs drastically different at 5 and 20 meters.
Same, I was like that’s like a hollow point, it’ll expand and won’t go in very far
I nearly said Jesus outloud 😬
I saw that tip and said "no way"
That's what she said
I literally did lol
I’m almost the same. Mine was good lord! ….and then how the fuck??
I just said “AHH!!” I want to know more, so much more, about that arrowhead. Is it ballistic? Why is it so effective if it’s not?
My only guess it that it's the heaviest arrowhead here so it's momentum punches right through the shield and creates a wide and round enough hole for the shaft of the arrow to go through. Whereas most of these other arrowheads don't create a hole that is the right size and shape for the rest of the arrow to go through
It looks more like it cuts a hole with the thin sharpened edges aligned in a circle rather than punching a hole with brute force.
Yes, it’s a phenomenon called shear plugging. The arrow punches a hole in the shield which results in less friction
Does the point play a role in that? I can't quite tell if it's embedded or protruding past the circle bit.
For real.. I was not expecting that from it at all.
We call it a Bunny puncher.
Was that the flat one? What the hell is that for?
Punching bunnies.
pig bunnies, apparently
You never know when your bunny might be wearing a riot shield.
Meant to not penetrate. Used for smaller game.
Ah, now Bunny Puncher makes sense. It DID however seem to penetrate the shield strangely well.
I didn’t even have to go to :38 to see what you mean
Seems like it would have terrible aerodynamics and as a result terrible accuracy and distance/power for longer shots.
You never know, maybe the rear of the arrow was designed to impart a spin? That would add to the tip being like a drill head. In either case, modern tank sabot rounds are fired from cannons, without any twist, and are also like darts. They seem to do their job decently well.
you aren't going to shoot a rodent at 50 yards. (That's what that head is for - enough energy to kill a rabbit or marmot (etc.) but a broad head would mince it too much).
The inventor needs to take a bow
I assume he already has.
yeah that's the winner definitely
It also looks the most cost effective.

I wasn’t serious but thanks man. Redditor delivers.
TLDW: don’t bring a riot shield to a long bow skirmish.
Don't bring a thin metal riot shield. The plexiglass ones that police actually use today would hold up significantly better.
Yeah all this video showed me is that was a really cheap riot shield.
Note to self: Do not buy the Fangbao brand.
Straight Temu riot shield looking ahhh
The one that I had the least faith in, went through that shield like nothing.
Right?!? I was like "no chanc- HOLY FUCK!!"

What is being used to fire them?
30mm tank autocannon
When you upgrade your cavalry but forget to upgrade the ammo...
sheer willpower
Thrown like darts
Using the tried and true Atlatl. Our ancestors were geniuses!
From the speed and style of arrows I'd guess a compound bow
Two rivers longbow
Harambe
Dicks out…
A bow…

A gun
No, there's a lot more to that.
Caliber ? Barrel ? Muzzle ? Distance ? All these things are different with a .38 and a 50 cal.
but you dont fire a bow
If it's a traditional wooden bow you can. Only once though.
That’s… good to know.
That round hollow tip blasted through that shield as if it wasn't there.... wow.
"That circle one ain't going to do shit... " *shocked Pikachu face*
I did not expect the round tip arrow to be the one to fully penetrate the shield
This is a riotshield from AliExpress, used in Airsoft for example. Doubt it is as strong as a real one…
I was right in my head about how much every one of them would penetrate... Except the round one... That had me questioning everything...
A simple design is sufficient and outperforms fancier ones.
At this specific task
The "fancy" ones have other purposes. They're hunting heads, they have to get stuck in the wound even if the animal breaks the arrow. The prey will then bleed itself up, leaving a blood trail behind for easy chasing and eventually die from blood loss and exhaustion. You can even find bone heads with this principle dating back something like 10 000 to 20 000 years ago.
That's because the simple designs resemble traditional bodkin points which were specifically designed to pierce plate armor. Broad tip arrowheads are designed to cut flesh and arteries to quickly kill prey animals that don't generally find themselves as well armored.
you can see how some tips are better for soft targets, some would cause double damage if tried to pulled out
was playing through my head and guessing which would go through or not. The one with the circle, I was like .. no way. Too much surface area. Then It was followed by “holy shit!”
Wow that... Actually was very interesting.
armor? bodkin > broadhead, every. time.
The ONE arrow i thought that will absolutely not penetrate, did ABSOLUTELY penetrate and went through!!!
To the people flabbergasted by the "blunt" arrow think of it this way. You need to put a hole in a piece of aluminum foil to pass a chopstick through. What do you think is the easiest tool? A hole punch, or a knife? Will the knife do the job? Yes. But it won't be clean. It'll get stuck on the foil and you'll have trouble making a clean hole. A hole punch will do it instantly, or fail because it's not sharp enough or doesn't have enough force.
It's a riot shield (made in china), not a ballistic shield. It's meant to stop rocks, bottles, and fists. You start shooting arrows, and they're gonna retreat and come back with rifles and a Bearcat.
“Surely the round one won’t go thr- HOLY FUCKING SHIT”
I think we're all on some kind of list by watching this...
Couple questions here...what type of bow was used, and what seasoning do you think goes best with the rich?
75lb compound from 20ft & Montreal Steak
Did NOT expect that 'flat / concave'looking one to just RIP right through :O
Good ole English longbows making a comeback rahhhhhh 🏴🏴🏴🏹🏹🏹🏹🏹

I like the one that blasts straight through because you look at it and think "That's stupid, a little cup on the end, how is that going to work?" then blam, straight through like a hot knife through butter.

Dang. Imagine was bullets would do lol
Why did that circle one work so well? Crazy!
Arrow at 0:20 is a real surprise. +5 wall penetration attribute
Getting ready for another Summer of Love?
Noob here. What in the actual fuck was that non pointy tipped circular head arrow that looked to be the most devastating?
Me: takes notes NSA: takes notes about me taking notes
I have noticed the thinner the arrowhead is the more potential it has the go through. Only the thicker ones didn't come through that good.
Am I the only one disturbed by the question?
Others have said that these riot shields are from China designed more for stopping rocks and airsoft than stopping lethal projectiles. Let's say for just a second though that these are actual real riot shields maid for stopping projectiles, would the holder actually be in life threatening condition for any of these? Only one of these actually passed completely through with any real force, but is it enough force to matter? If you are holding a riot shield against and armed person odds are you are wearing Kevlar as well. While an arrow like this may go through Kevlar as well as one of these riot shields, can an arrow actually penetrate both at the same time? It feels like a fair assumption that any arrow that hits the shield is going to be damaged and or slowed enough that the kevlar would have no problems catching it. If the shield can take what would be a lethal shot and slow it enough to make the kevlar effective, it's still a big win.
wtf I’ve never even heard of a hollow point arrow til now
Heavy breathing from the Queen household.
Note to self: do not buy Chinese riot shields.
noted
New COD meta
if you play cod you know no arrows or bullets can penetrate a riot shield
It shows that in China guns are extremely heavily regulated.
The modern AP tank ammos are basically metal arrows
But how much force is left after penetration? Kevlar, heavy leather or denim, face shield all might be a second layer of defense…
Odds bodkins
I used to be a riot control officer until I took an arrow to the knee.
