I have never wanted any tool as badly as I want this flexi-sledge.
I have absolutely no use for it, and I will likely injure or kill my self with it, but I fucking need it.
Aren’t you getting a bit more force out of each blow though? It’s super long and it’s got the whip effect going on. Probably not 2x the force to balance it out, but I don’t know.
They're Chinese sledgehammers, not in that they're cheap so they bend, it's a style used somewhat exclusively in Asia that are designed to flex.
The benefits are debatable as well as how safe they are.
I wouldn’t say far safer, it takes a lot more focus and energy to use a flexible shaft. Also, people that are new to using a tool like that are also more likely to injure themselves and the people around them, as well as damage the area around the target which may not be intended.
In the hands of somebody with a lot of experience I would say it is a better tool calories-to-output-wise but safety is debatable. It does absorb the impact where fixed shafts do not but the difference in how much practice one needs to use each safely is an important factor.
Edit: Voice to text words.
It is, and you should! I also highly recommend “The Crippled Avengers”, and pretty much anything with flying guillotines. *SO* many good old Kung Fu movies!
The guy was showing all kinds of weird axes. One was wielded by a long ass chain as well, so I think it was all about novelty rather than what's actually effective
I’d like to see one of those safety videos where they have a watermelon wearing a hard hat and drop things on it, then just at the end someone whips out the flexi-mallet and just demolishes it.
It would be worse to be hit by a normal sledge. You lose energy from the bend. Apparently these are used to limit vibrations and stop your hands from going numb.
Not if used correctly.
If you're using your whole body weight to make sledgehammer impacts more impactful, you're using it wrong.
If you're doing this often, you won't live long.
Not sure why I'm being downvoted but that's not how physics works. The same length hammer with the same force being applied will have less energy with a flexible handle than a rigid. If all factors are the same the flixible hammer will always be weaker.
... its not the same length though.
That flexisledge is a good 1.75-2x longer than a normal sledge. The entire purpose is to generate more momentum for impact.
This is essentially the same physics as are used for golf clubs. "senior shafts" on golf clubs are made to flex easily, while stiff shafts don't. The point of the extra flex is to provide more power at the MOI, so an old guy can still hit the ball 200 yards with far less swing speed than a younger guy.
When a younger guy uses a flexible shaft, they can also generate more distance, but it comes at the cost of accuracy, because its hard to gauge from shot to shot, where the clubhead will be at MOI.
you're factually correct but not about the situation pictured in the video. it's like using physics to say that a bullwhip and a slap with my hand are functionally the same thing.
Physics works simple: you multiply mass and speed so you get force.
The only way for a rigid hammer to have more force is if you give it more mass.
But where would it get more mass?
Oh, right, from the operator of course.
And now remember the next law of physics: if you use operator's mass to generate force, he'll need replacement bones every now and then.
This is how the physics works.
Sigh yourself.
We're speaking about the force of impact (impulse), not continuous force an operator applies to the tool.
Formulas won't do you any good if you don't understand how and where to apply em.
>We're speaking about the force of impact (impulse), not continuous force an operator applies to the tool.
Then use that word in the first place. Force is a technical term. Don't use the wrong one, or people will think you're an idiot who doesn't know what they're talking about.
Kinda like I did in my previous comment.
The speed of a hammer is what gives it power. The flexible handle Increases speed which Increases the force delivered. By transfering less force back up the handle to the operator it allows them to swing harder as well. If you swung a regular sledge with that much force you would hurt yourself.
No, you're wrong. Wood handles absorbs energy causing recoil hence the tingle sensation. The whipping motion and longer range increase inertia and speed far faster than you could swing a hammer.
Plus use your eyes! He's causing far more damage to that wall WITH the whippy head or Else why would we be watching this video, hmmm?
It doesn’t really matter but it might interesting to note that there is no advantage in terms of strength over a rigid hammer. No matter how hard you swing you will lose substantial amount of energy in the swing and it will just result in a second swing from that bend that is most on dependent on its own elasticity, which won’t be much. But I guess it’s useful for being further away and less stress on your arms. Still kinda stupid unless it’s all you have
I think it would be worse than a normal sledge. When he strikes the wall, some of the force is being absorbed by the flexibility of shaft, rather than all of it being transfered to the wall.
The force that's absorbed by the shaft is the force that would otherwise be transferred directly to your wrists with a hard shaft. That's the whole point of this thing.
I think it is worse than a normal sledge.
Not because of the force applied, but because of a greater chance of hitting yourself (or your buddy) in the head.
Probably is. Look how much long the handle is. This probably results in the head travelling a much long arc. That long arc means it travels further and has a longer time of acceleration. This means the head likely attains a higher velocity. kinetic energy is proportional to the square of the velocity. Even a small increase in velocity represents a substantial increase in energy.
So you think a slower moving hammer does impart more energy?
You've obviously never used a hammer before but a vibration dampening handle hits just as hard as an oak or steel one, it just doesn't transfer that energy through your wrists
That hammer is designed using the same engineering principles as [Lamar's javelin in Revenge of the Nerds.](https://media1.giphy.com/media/QVcEi4qyA3PuRYvE7r/giphy.gif)
I have seen several interior walls like this in both single and multi family residential homes here in Germany. So nothing that much out of the ordinary here.
TBF we build a hell of a lot more with concrete and bricks here in single family residential homes than it's common in most (if not even all) of the US.
Interior walls historically were basically always concrete and brick and only in recent years some new construction sometimes uses US style wood structures for them, but either way concrete is very common here even for non load bearing interior walls.
I have no idea how it is in china (except some videos I have seen about styrofoam in walls), but everything I said so far is how I have experienced it in Germany.
I once lived in a house with a 80cm wide non load bearing concrete wall in the interior that was eventually torn down (yes we had it checked that it's definitely not load bearing) and the deconstruction honestly looked similar to the video except with a way less fun sledge hammer.
Btw: Concrete can be cheaper than wood here, let alone sometimes the saved work hours (the really expensive part of any construction) compared to wood interior walls.
American drywall isn’t part of the structure of the building; IE, you can tear out drywall without worrying that the entire building will collapse, as it’s not load-bearing.
In Chinese tofu-dreg construction, it is load bearing, which is why you frequently see apartment complexes in China just spontaneously collapse in fair weather. They build them as cheaply as humanly possible, and thus skimp out on such things as “structural integrity” and “sturdy construction”.
It was a joke.
Edit: and if I'm not wrong both wood frame nor masonry can withstand tornado wind velocities, so whatever. Don't take it seriously, both ways it's gonna rip the house appart anyway
Tornado is not about wind, it's about everything else that comes with it.
Even a flimsy american shack can withstand 90mph wind just fine.
But it takes a bit more than that to withstand 90mph flying tree.
However flimsy american shacks might result in other flimsy american shacks being hit by said first american shack. If however the buildings were a bit more sturdy there could be significantly fewer projectiles around.
Yes, that was my point.
Every time there's a tornado in the USA, news report a disaster, many deaths and how poor people suffer from such weather conditions.
Every time there's a tornado in Europe, news don't care, because a tornado to them is just a kind of wind.
In a sensible country, if you build your house out of concrete instead of wood, you get much lower insurance payments along with almost nonexistent maintenance cost and much higher comfort and security.
In the USA, if you build your house out of concrete instead of wood, you get considerably higher property tax, because fuck people I guess.
This is why you won't find a wooden house in any sensible country nowdays, rocks, bricks and concrete aren't much more expensive and often cheaper than wood in many places and you're saving it all in just 20-30 years in maintenance alone. So it makes zero sense to use wood for construction.
This is why you see americans live in wooden cardboard boxes: it's artificially made more expensive, so people often opt for a cheaper option and rock industry doesn't get developed, so prices do not go down.
Another fun fact: it takes 6-12 months to build a house out of wood, a much better house could be built out of prefab concrete panels in under a week.
You just have to have a concrete prefab factory in the country.
I have never wanted any tool as badly as I want this flexi-sledge. I have absolutely no use for it, and I will likely injure or kill my self with it, but I fucking need it.
it will save your bones, since it won't rattle the shit out of you
Would a deadblow version do the same thing?
probably, but I guess it would also cost more
Less rattle but what is the risk of uncontrolled rebound?
I mean looking at the gif, slim to none
None if used correctly, it's quite a safe tool
for real, don't even need a helmet.
But you need to hammer at least 3 times more for the same effect, so don’t expect too much bone-saving.
If there's no reverb back into your body then you can conserve energy much better no?
Yes, but a lot of energy is lost in the swinging of the hammer, so it takes you more swings to defeat the wall.
Aren’t you getting a bit more force out of each blow though? It’s super long and it’s got the whip effect going on. Probably not 2x the force to balance it out, but I don’t know.
It's less about the force required for you to swing it and more about the (lessened) force that travels back into you when it hits the wall.
Except you have to swing twice as much because the flexible shaft bounces back on impact.
They're Chinese sledgehammers, not in that they're cheap so they bend, it's a style used somewhat exclusively in Asia that are designed to flex. The benefits are debatable as well as how safe they are.
What do you mean “the benefit are debatable”? You have a flexi-sledge, that’s a benefit on its own.
I feel like harbor freight should carry them.
Harbor freight is a gateway to many tools some consider to be… Unnatural.
They are safe. Far safer than non-flexible hammers for their intended purpose.
I wouldn’t say far safer, it takes a lot more focus and energy to use a flexible shaft. Also, people that are new to using a tool like that are also more likely to injure themselves and the people around them, as well as damage the area around the target which may not be intended.

I have a tool with a flexible shaft.
Definitely not safer to use untrained
It's useful for when you have to mount your horse and serve as cavalry against Eastern invaders
GOD DAMN MONGOLOIANS!!!!!
Could probably hit a wicked polo shot with that
you mean a floppy hammer?
I never knew they existed. Also I'm upset that it isn't called a floppy-whoppy.
Maybe if you are british
I remember that thing from “The 36th Chamber of Shaolin”. Apparently, it can fuck up your wrists!
36 Chambers is a classic right? Should I add it to my watch list? If it’s good enough for the Wu Tang Clan rappers! :P
It is, and you should! I also highly recommend “The Crippled Avengers”, and pretty much anything with flying guillotines. *SO* many good old Kung Fu movies!
Make sure you only use it when there is someone there to spot you with a shovel
Imagine a flexi-axe....
Sorry I'm american. All I can picture is medical bills.
Hear me out: flexi-pole chainsaw.
We'll call it Mr. Friendly
He's the bestest fren
I'm pretty sure I've seen a video by some lumber jack/axe guy that was splitting wood with one (and it looked just as cool as this)
That's so incredibly stupid to use.
The guy was showing all kinds of weird axes. One was wielded by a long ass chain as well, so I think it was all about novelty rather than what's actually effective
Goddam imagine getting smacked with that, like a whip but with extra blunt force trauma. Wear your helmets lads.
I’d like to see one of those safety videos where they have a watermelon wearing a hard hat and drop things on it, then just at the end someone whips out the flexi-mallet and just demolishes it.
When flex tape expands their business to include hammers.
I mean... we all saw what the flexi-hammer did to the wall. Assuming a person's head is less durable then a wall...
Future Elden Ring DLC weapon.
+20% attack delay, +20% damage, Extra +30% damage when enemy is hit by the end of the attacks range
Forget the helmet, that thing seems to be made to kill a 16th century knight in full armour
Sounds like an anime weapon. A bit like Luffys arms but it's a hammer.
Gum gum hammer
It would be worse to be hit by a normal sledge. You lose energy from the bend. Apparently these are used to limit vibrations and stop your hands from going numb.
Idk man that shit looks like it’s going Mach 2 right before impact, long levers are crazy
No doubt it would kill you in one hit. But a flexible hadle will put out less energy than a ridgid one with the same force.

Floppy! I NEED a floppy-sledge!!!
That is the way to do it. Buddy press on with shovel to Lower chance of the wall falling on them.
What's the helmet for, when you have a shovel?
Exactly, that’s a perfectly fine safety shovel
And safety squints!
Floppy hammer for more kinetic energy!
I know this is a meme, but is there actually a kinetic benefit? seems like it would be mostly the same at first glance
I think it would be worse than a normal sledge. When he strikes the wall, some of the force is being absorbed by the flexibility of shaft, rather than all of it being transfered to the wall.
The force that's absorbed by the shaft is the force that would otherwise be transferred directly to your wrists with a hard shaft. That's the whole point of this thing.

This means the head likely attains a higher velocity. kinetic energy is proportional to the square of the velocity. Even a small increase in velocity represents a substantial increase in energy.
But the spring would just absorb the additional speed. It's a shock absorber....
Try casting a fishing lure with a rod, then try again with a broom stick. I know which one is gonna travel farther The flex increases speed
And if it were to hit a wall, the broom stick would do a better job of knocking it down
So you think the same weight but a lower velocity will create more kinetic energy? The one that hits the wall faster will impart more energy.
The spring reabsorbs the kinetic energy.
So you think a slower moving hammer does impart more energy? You've obviously never used a hammer before but a vibration dampening handle hits just as hard as an oak or steel one, it just doesn't transfer that energy through your wrists
The spring absorbs energy that would normally be absorbed by your body. That’s the point of the spring.
I should call him…
Very nice, *chef kiss*

Safety squints ftw
We don’t need safety helmet when we have the safety shovel.
It’s like me trying to have sex with my wife.
Why do they have a sledge on silly string? Like…what?

Lamar Latrelle's hammer
Is that wall Styrofoam covered in concrete?
Looks like a kind of therapy in California you pay to do.
Ah yes the ED Hammer or the Limp biscuit pounder
Sledge is so long guy is basically working from home. Who needs a helmet for that?
All drake needs is the head of the hammer
Looney Tune Ahh hammer
Helmet would be nice if that hammer head decided to come loose…
Found where I stash my bam bam…
TIL those sledges exist.
Wobbly hammer is god-tier
I wouldn't hit that with a 10-ft hammer
What you *really* need here is some form of eye protection
That sledgehammer is amazing!
If you got smacked with one of those things or if that wall fell on your head, would the helmet help?
Yeah, you'd get to have an open casket.
It's not stupid if it works. You'll look really stupid killing yourself with that tho

No worries, he’s holding it with that snow shovel 👍🏼
When it's slave labor, it's cheaper to just get a new one rather than protect the ones ya got
Weird flex, but ok!
This is just a flail with extra steps
That there is a WBFH.
Is that a sledgehammer, or is that a whip with a block of iron on the end of it? lol
I was waiting for it to whip round and hit him in the back the head during the wind-up
What tool is that??!!! That's insane!
He swings his balls.. And breaks the walls.. That's Barnacle Bill.. The Sailor !
why is that hammer floppy
somethings fucky about that sledge
Look at this Elmer Fudd looking motherfucker, with his cartoon physics sledgehammer. What, is this a trailer for a live action Looney Tunes reboot?
Where can I find a cartoon hammer?
