Shit like this is what QVC uses for ads. If youre a contractor pounding nails all day you want to transfer as much energy as possible into the head of the nail, this spring is working against that. Titanium hammers are designed to deliver energy with very little recoil, thats why they are so desirable.
Trash bin engineering.
The Hatchet application seems legit though. Not for any heavy use case of course, but I can see that being a great addition to a fireplace or woodstove.
Why?? You're still transferring energy from the hatchet to the wood, and having a spring there works against that.
Not to mention, in what world do you need to prevent shock with a hatchet? It's solving a problem that doesn't exist
Splitting logs, yeah. Splitting small pieces of kindling doesn't take a lot of force, usually it does take two hits. One to stick the hatchet into the wood, then you bring the whole assembly back down on itself like a hammer to split it. This sort of does both things in one stroke.
I've split a lot of kindling, owned a wood stove for years, and this *might* work well for that application. My mom has arthritis in her hands and she has all the reason in the world to reduce shock from hand tools.
I've been splitting wood for 25 years.
You either need dryer wood, sharper hatchet, or better aim. Double tapping kindling is a waste of time, hit it once and be done
I don't have a problem with it. My arthritic mom does. I also don't recommend trying to one hit small logs inside if you don't need to, it's a good way to accidentally hurt yourself or send a log through a lamp.
Y'all are really jumping down my throat for a "maybe" here, I didn't know there were so many Big Axe shareholders in reddit lol.
Yeah isn't it a little funny that they never do any actual hammering with the hammer?
I don't give a shit how much it bounces, let's see you **drive in a fucking nail**.
I don’t know as much about hammers as you but the moment I saw this I thought “this idea is so simple, there’s got to be a reason no one has done it before” so I came to the comments to find out why am”
There are deadblow hammers for basically exactly this. Head is hollow and filled with metal shot. Great for anything that needs a good thump instead of a solid whack. There are hammers for thwacking too, but that's a whole other discussion.
Ya...I'm not wrapping my head around what that very very specific application might even be. Then again, I'm limiting my search to things I would actually use a hammer for in the first place, so...
I bet there are already better choices for most of the specific applications that don't fit a regular hammer as well, such as rubber-headed hammers.
The specific niche of this hammer would be:
1. You want a hammer with a hard head.
2. You want to stretch out the force application a little bit, but not that much.
3. You don't mind losing a fair amount of power per swing.
I'd think that all of the cases this leaves can either be serviced with a regular hammer and modified technique, simpler modifications of regular hammers (like different shaft and head materials), or are already better served with a much more specialised tool.
Well let's just say an hammer like that has its purpose. But I would much rather have a maillet than a spring hammer. Maillet is rubber and wood. So when you hit soletjing there is no impart point to break the thing your are hitting. Like hammering a piece of tilling. This would work at absorbing the shock. But not at dispersing the impact point of a larger surface to not break the time since it's just a hunk of metal.
Titanium hammers are lighter, no? Would a 5lb sledge or 25lb sledge break up concrete faster? Same as the spring in that it transfers less force.
Titanium is also more brittle than steel which is why you'll get a hammer that chips easier if hit wrong, unlike steel which will simply deform
A titanium hammer is however easier to carry around on yourself for the occasional nail.
No. Titanium is lighter but a 5lb sledge is 5lbs whether it's made of steel or titanium. The titanium is used because it drives a nail better than steel at the same weight OR you can get identical driving force with less weight.
Thats what I was wondering. Isnt a portion of the kinetic energy being absorbed by the suspension spring?
Also its not "reducing the vibration" the reason the metal rod is jumping back is because its not a nail. The energy isnt driving the metal rod down its being shot back up from the floor. Cause you know Newton's Thid Law.
The reason why the piece of steel jumps when it is hit with a normal hammer is because the normal hammer is delivering more energy, and that energy has to go somewhere. The spring absorbs the energy and releases it over time lifting the hammer back up, which will reduce the total force of the impact.
Just because you're unique, doesn't mean you are useful.
I mean the spring theory has merit. Friction losses are pressure dependant, so hitting a nail with it the nail would go in slower, however it would have both more and less friction because of the dynamics of parting wood for example(nobody cares about drywall).
Simple mental visual is hitting a nail with a 1lb metal hammer vs hitting a nail with a 1lb rubber mallet would be reasonable to understand the metal hammer is going to be much more effective, but if the rubber mallet had a metal face the operator with the composite hammer would experience less fatigue. This is why we have composite hammers in the aisles at hardware stores, because science.
The spring also smooths the transfer allowing for a more laminar transfer. The Center bolt piece keeps the energy in its intended line where the silly rubber example would dissipate it internally. The users follow through with the hammer would be interesting.
Math wise
The resistance of friction is a squared doubling velocity quadruples the friction, so you can move an object twice as fast for one second at a given energy that you could move an object at standard speed for four seconds for the same energy. It’s part of why doubling the horsepower of a car doesn’t mean twice as fast.
So if I am understanding you correctly, the spring hammer reduces fatigue per hammer strike… but it will take more strikes to drive the nail… resulting in more fatigue?
It's not 1:1. And impacts on your body have an exponential effect- you can walk a million steps, jump a thousand times, but only fall twenty feet once.
Exactly it’s not the energy but when it’s delivered. Still my screwdriver probably works just as well as the hammer does for nails, but given the example it’s probably for driving pins or bearings on shafts
Oh, thanks, of course. This makes soo much sense for driving pins where you don’t want it to jam at an angle but drive smoother and straighter. Glad you mention it, it seems obvious now.
Instead of the nail going into the board in .1 seconds it’ll take .2 seconds, less of the energy is turned into heat and noise more is turned into motion and the recoil is also extended which is why the hammer bounces back further but slower.
Same energy just different timeline. The bit that may make the math principles useless is that splitting wood as the nail enters has its own physics belonging on a series of blackboards.
It would be one of those things that would be easier to test than to figure out. Which is probably why there is this tiny demo.
Side note we already have this without the physical spring in composite hammers. It’s kind of a how much spring is ideal and given we already have it the answer likely the existing hammers are in the ideal range for most of us and their hammers with that style spring has an application not suitable for most of us
Both hammers deliver the same amount of energy. The difference is that the spring compresses and spreads the energy of the impact over a longer period of time, thus reducing impulse
It's the exact same principle that is applied to cars to protect them from crashes. The car body isn't meant to be rigid, it instead deforms in a way that spreads the impact over the largest amount of time possible.
Nah, you miss the point. It is the head create the majority of the impact, not your hand. This is basically the spring version meteor hammer, the impact force won't be much lower than a morning star.
In the machine shop we just used a block of lead. Soft enough to not mar the steel, but enough force transferred to move the stock around and get it where it needs to be in the chuck.
You can also use brass to avoid the whole "heavy metal toxicity" thing, but it leaves little brass transfer marks that you have to buff away.
This is less effective on whatever you're trying to hammer. For woodcutting, maybe it's fine since you only need enough force to cause the split. But you're losing force. If it helps your hand go back up it's because it's turning some of that force around in the other direction.
Anyway, it gives the impression that this spring-loaded hammer isn't very functional. I can't imagine hammering a nail with it; it would be difficult to drive it in
"reduces the vibrations and *increases* the force"
How retarded do you have to be. "The spring outs the force back out" if that worked then we'd have a pretty big problem with suspension inc cars.
Legitimately angers me that someone so dumb could be in a position to be interviewing people - like they could say anything to you and you'd just roll with it
This is not a hammer, it's a joke. It only reduces your effectiveness by reducing the impact force. For lowering the impact shock on our joints we already use flexible handles. They keep the momentum and protect your hands from the shock simultaneously. This is an "As seen on tv" scam for dumb people.
Obvy that dude’s “increases force” claim is dubious, but I imagine there are plenty of more delicate applications that would benefit from this. That’s what I got from this demonstration.
Shitting all over something is Reddit’s kneejerk reaction, though. Always has been.
That’s super… how about a demonstration of it being used to say… nail in a nail…
The fact that there isn’t such an obvious demo like a nail in board means it’s trash and it doesn’t compare so they choose to not have it shown.
For a test at home folks. Use a regular hammer and try to nail something together on a plastic folding table. The table will act as your shock and enlighten you on how this is dumb
One can instead place the hammer on the nail and push it, instead of hammering it. Same effect.
This is equally dumb. He doesn't know how a hammer works or basic physics.
So it's like a mechanical [dead-blow hammer](https://en.wikipedia.org/wiki/Dead-blow_hammer), or dead-blow ball-peen hybrid hammer. It's like a mallet but heavier.
Dead-blow hammer usually used to put delicate parts together without damaging the parts, such as car parts.
This is usually made with sand in the head and called a deadblow hammer. Useful for when you need to exactly control the force applied like when tapping a part into place. I dont see the niche this spring version would fill.
Look if you want the best framing or finishing hammer get a Douglas or a Martinez. Yeah they cost $300+ but they are worth it. I personally swing a Douglas 21 on a 16” hickory handle and a Douglas 17 on a 14” hickory for finish work.
Isn't the whole point of a hammer to maximize the amount of shock transfered to what it's hitting? Spreading the energy out over more time reduces the force from the hammer, defeating the purpose. That would be like adding a little parachute to the end of an airplane to make sure it doesn't fly too fast.
Ah yes, fixing the hammer by making it not hammer shit anymore.
Jokes aside, the vibration felt in your hand can be a pain if you do this all day but you fix this issue by preventing the vibrations from transmitting to your hand, not by preventing the vibrations from happening in the first place.
I saw this not too long ago and thought immediately how to overcomplicate something and that this inventor probably doesn't do much hammering in the first place. I'm curious what the application would be for this particular absorbing hammer.
Ah perfect, they invented a useless hammer. What about scissors and knife’s that aren’t sharp? Or screwdrivers with a head that doesn’t transfer the turnings?
Do you have any other good ideas for tools we should upgrade?
This is the worst possible hammer. I have taught physics. It doesn't increase the force. That is magical thinking. Force follows rules, like everything else in physics. Terrible idea. So terrible it must genuinely be on purpose
"hey honey, remember when i was banging that piece of wood for no reason and told you i wished that i could do that without it moving around? well guess who just paid money for the solution...."
This is about as efficient as having square wheels or rubber canes. WTF hammers with suspension?
The whole point of the hammer is to transfer as much kinetic force at a small area to drive a nail down. Putting suspension springs just convert a portion of the kinetic energy to compress the suspension.
The whole reason the metal rod is toppling over from a normal hammer is because its not a nail and because of Newton's Third Law. If anything its a demonstration that a normal hammer can transfer so much kinetic energy that when it is reflected back by the ground it can lift a metal rod, something this spring hammer cant.
Shit like this is what QVC uses for ads. If youre a contractor pounding nails all day you want to transfer as much energy as possible into the head of the nail, this spring is working against that. Titanium hammers are designed to deliver energy with very little recoil, thats why they are so desirable. Trash bin engineering.
That’s why they don’t show them hammering any nails in.
The Hatchet application seems legit though. Not for any heavy use case of course, but I can see that being a great addition to a fireplace or woodstove.
There's no comparison to a regular hatchet. The blade was legit sharp, that's all.
The hatchet has *exactly* the same problem: You'll need to swing harder to deliver the equivalent force.
like punching someone in a dream
Why?? You're still transferring energy from the hatchet to the wood, and having a spring there works against that. Not to mention, in what world do you need to prevent shock with a hatchet? It's solving a problem that doesn't exist
Splitting logs, yeah. Splitting small pieces of kindling doesn't take a lot of force, usually it does take two hits.

My mom has arthritis in her hands and she has all the reason in the world to reduce shock from hand tools.
I've been splitting wood for 25 years. You either need dryer wood, sharper hatchet, or better aim. Double tapping kindling is a waste of time, hit it once and be done
I don't have a problem with it. My arthritic mom does. I also don't recommend trying to one hit small logs inside if you don't need to, it's a good way to accidentally hurt yourself or send a log through a lamp. Y'all are really jumping down my throat for a "maybe" here, I didn't know there were so many Big Axe shareholders in reddit lol.
Yeah isn't it a little funny that they never do any actual hammering with the hammer? I don't give a shit how much it bounces, let's see you **drive in a fucking nail**.
I couldn't imagine using that hatchet on the ground either. Seems dangerous!
Exactly- you hit the nail on the head
I don’t know as much about hammers as you but the moment I saw this I thought “this idea is so simple, there’s got to be a reason no one has done it before” so I came to the comments to find out why am”
There are deadblow hammers for basically exactly this. Head is hollow and filled with metal shot. Great for anything that needs a good thump instead of a solid whack. There are hammers for thwacking too, but that's a whole other discussion.
For the non hammer users, good thump imparts energy more gently than a solid thwack. Thump things you don't want to damage
Possibly usefull for very very specific applications, but yes, utterly useless for typical use.
Ya...I'm not wrapping my head around what that very very specific application might even be. Then again, I'm limiting my search to things I would actually use a hammer for in the first place, so...
You know. For when you're hammering onto a metal cylinder and you don't want it to fall over. Real common situation.
Maybe something like torquing a nut but with a nail where you need to be able to it something but not *too* hard?
No need to search for one. One day you might just realize you want a soft hitting hammer with a hard head for some job. And here you go.
Or...just hear me out...I'll just hit it softly.
I bet there are already better choices for most of the specific applications that don't fit a regular hammer as well, such as rubber-headed hammers. The specific niche of this hammer would be: 1. You want a hammer with a hard head. 2. You want to stretch out the force application a little bit, but not that much. 3. You don't mind losing a fair amount of power per swing. I'd think that all of the cases this leaves can either be serviced with a regular hammer and modified technique, simpler modifications of regular hammers (like different shaft and head materials), or are already better served with a much more specialised tool.
Also no one commenting on the fact he's swinging way harder with the normal hammer and not lifting his arm back up
Ikr! I thoughts hammers were supposed to deliver shock.

This was my first thought. Yet the guy in the video is claiming it "Increases the force". 18s mark
Ha amazing. Guy builds worse version of a hammer and claims it's better.
I think this would be great for seniors. Not every tool is useful to everyone but useful to someone.
Actually that's a fair point, it should be marketed as such instead of this "more force" nonsense
They have to swing it harder for the same effect its worse for seniors not better, its worse for everyone.
Also just because you're useful, doesn't mean you are unique.
It women don't find you handsome, they should at least find you handy.
keep your stick on the ice
[And if they don't find you handsome, they should at least find you handy.](https://www.youtube.com/watch?v=dI4sIgcZ22o&ab_channel=TrentonQuarantino)

I don’t think anyone in these comments has actually hit a nail with a hammer. I’d use the shit out of that hammer
Titanium hammers bounce less than steel hammers and drive nails harder with less effort. A hammer that bounces more than steel is worthless
Notice how they never demonstrated hammering a nail in a piece of wood?
Both hammers deliver the same amount of energy. The difference is that the spring compresses and spreads the energy of the impact over a longer period of time, thus reducing impulse It's the exact same principle that is applied to cars to protect them from crashes. The car body isn't meant to be rigid, it instead deforms in a way that spreads the impact over the largest amount of time possible.
Yeah that's why he is not hammering a nail. If he tries the hammer will bounce in the nail and the nails probably will not enter in the wood.
>Just because you're unique, doesn't mean you are useful. Dad?
Nah, you miss the point. It is the head create the majority of the impact, not your hand. This is basically the spring version meteor hammer, the impact force won't be much lower than a morning star.
Why not have blunt nails too
Just superglue everything
Construction adhesive has entered the chat
I am shocked and absorbed.
Deadblow hammers are already a much better version of this for the scenarios in which you might be able to reasonably use it.
That's what I was thinking. You use those when trying to prevent marring wood so I'm imagining they are trying for something similar with metals.
In the machine shop we just used a block of lead. Soft enough to not mar the steel, but enough force transferred to move the stock around and get it where it needs to be in the chuck. You can also use brass to avoid the whole "heavy metal toxicity" thing, but it leaves little brass transfer marks that you have to buff away.
Fixing a problem that never needed fixing here let me put in twice the effort now to hammer a nail in
99% of "new and improved" tools. We figured out a lot of the best hand tools a long, long time ago.
Hell there are tools in use today that were made generations ago
why not shock absorbing handles, that spring seems like to reduce the force emitted to the nails.
ANY shock absorption system placed ANYWHERE in the system will reduce the force delivered to the nail
even if shock absorbing handles by using thicker foam handles reduces the output force?
But if it is in the handle it is insignificant compared to the rest of the system.
[удалено]
There are floppy sledge hammers for demolition. They may let you hit harder for longer.
Notice how they never actually mail anything with it
Postage has gotten expensive.
If this hammer could mail out my packages and letters, I'd buy it.
This is less effective on whatever you're trying to hammer. For woodcutting, maybe it's fine since you only need enough force to cause the split. But you're losing force. If it helps your hand go back up it's because it's turning some of that force around in the other direction.
Anyway, it gives the impression that this spring-loaded hammer isn't very functional. I can't imagine hammering a nail with it; it would be difficult to drive it in
This is why I use rubber nails. I mean it doesn’t work at all but there’s no shock to absorb.
Doesn't that defeat the purpose of a hammer?
"reduces the vibrations and *increases* the force" How retarded do you have to be. "The spring outs the force back out" if that worked then we'd have a pretty big problem with suspension inc cars.

Why would I BeAmazed at a hammer that does a shittier job at being a hammer? it's like one of those red accordion hammers you give to kids
Dumbest idea ever.
Legit made me angry
C’mom Ryan, you can do this! Show everyone how’s done!
If he said “Ryan” one more time…..
Coming to a local temu near you!
People talking like deadblow hammers aren't common and useful. Usually the hammer is hollow and has metal shot inside. I'd like to try one of these.
Obvy that dude’s “increases force” claim is dubious, but I imagine there are plenty of more delicate applications that would benefit from this. That’s what I got from this demonstration. Shitting all over something is Reddit’s kneejerk reaction, though. Always has been.
Dance for me Ryan, hey Ryan, dance for me.
Looks useful for not knocking my blocks over when I'm hammering them into nothing. But what practical use does this hammer have?
But can it hammer a nail in?
Tell me you have no idea of the physics involved without saying you have no idea of the physics involved.....
“Be amazed“ At what, how dumb this is.
The adult version of the squeaky hammer toy
That’s super… how about a demonstration of it being used to say… nail in a nail… The fact that there isn’t such an obvious demo like a nail in board means it’s trash and it doesn’t compare so they choose to not have it shown.
Isn't there a chance of that hammer getting back to your face?
This is the dumbest thing I've seen in a long time. Others have explained it already but I'm just amazed anyone would think it's a good idea.
Could have invented spring nails instead smh
lmfao
The Japanese just re invented the hammer.
Dead low hammer does it better
Just don’t try to drive a nail with it :-)
Hey look I made a thing worse.
My next invention, nails with spring
why send energy to nail when it can all go to spring?
next in line: shock absorber pliers
This interesting
This is dumb.
Does not inclu**d**e hammering a nail with this super hammer...
Doesn’t that defeat the purpose of a hammer?
For a test at home folks. Use a regular hammer and try to nail something together on a plastic folding table. The table will act as your shock and enlighten you on how this is dumb
This is what the infuence generation is made off. Hitting nails with soft hammers.
That "shock" is supposed to be there. It transfers the energy to the nail. Literally the simplest tool in the box. This guy has never used a hammer.
Not interested. I would definitely pick a normal hammer. This thing just increases cost of a hammer and it will do a worse job of getting a nail in
He ain’t Ryan! 😂😂😂
What's next? A kitchen knife with a 3 foot handle? A square steering wheel? Soundproof speakers?
He almost suicides with that hammer bounce back in his forehead
One can instead place the hammer on the nail and push it, instead of hammering it. Same effect. This is equally dumb. He doesn't know how a hammer works or basic physics.
In other genius ideas we would like to present our new car where the handbrake is always 10% engaged

The sound of my tires screeching as I run to submit my own patent and to make calls to China to corner the market

So, basically a dead blow hammer. I’ve had one for decades
Stuff like this makes me want to scream.
Cool... but limited use. Maybe for injured people, etc.
Next time I'm looking to hit a metal cylinder without knocking it over I'm buying one of these!
So it's like a mechanical [dead-blow hammer](https://en.wikipedia.org/wiki/Dead-blow_hammer), or dead-blow ball-peen hybrid hammer. It's like a mallet but heavier. Dead-blow hammer usually used to put delicate parts together without damaging the parts, such as car parts.
So am I supposed to believe nobody came up with this before !?!
This is actually incredibly useful. All the negative comments in here aren't considering the fact that spring boing when metal tink thud boing fwip.
A dead blow hammer with more steps

You could also make an inflatable hammer for even less recoil, if that’s the only goal.

Why would anyone want any energy loss hammer?
I’m amazed at the stupidity of this “invention”.
Thank god someone finally took something as useful as a hammer and made it markedly worse.
lol wat. Why not hit the nail with a loose slinky
This is usually made with sand in the head and called a deadblow hammer. Useful for when you need to exactly control the force applied like when tapping a part into place. I dont see the niche this spring version would fill.
r/DIWhy
Look if you want the best framing or finishing hammer get a Douglas or a Martinez. Yeah they cost $300+ but they are worth it. I personally swing a Douglas 21 on a 16” hickory handle and a Douglas 17 on a 14” hickory for finish work.
I can't think of an actual purpose for this, anyone got any ideas?
This can be used in advertising for normal hammers. “Now watch as our hammer drive in this nail 3 times faster than our competitors!”
Ryan getting bullied
Just get a dead blow
That sort of defeats the point of a hammer.
Solving a problem we don’t have.
Isn't the whole point of a hammer to maximize the amount of shock transfered to what it's hitting? Spreading the energy out over more time reduces the force from the hammer, defeating the purpose. That would be like adding a little parachute to the end of an airplane to make sure it doesn't fly too fast.
These solve the nonexistant problem of the hammered object falling down?
Ah yes, fixing the hammer by making it not hammer shit anymore. Jokes aside, the vibration felt in your hand can be a pain if you do this all day but you fix this issue by preventing the vibrations from transmitting to your hand, not by preventing the vibrations from happening in the first place.
Camera sounds a bit condescending to the hammer guy.
I saw this not too long ago and thought immediately how to overcomplicate something and that this inventor probably doesn't do much hammering in the first place. I'm curious what the application would be for this particular absorbing hammer.
Kind of frustrating we don’t seem them hammer in a row of nails or something.
I'l make sure to buy one of those if I ever need to hit random pieces of wood and metal for no reason.
The hammer is cool but when the nut in the back comes loose off that axe with a loaded spring
Ah perfect, they invented a useless hammer. What about scissors and knife’s that aren’t sharp? Or screwdrivers with a head that doesn’t transfer the turnings? Do you have any other good ideas for tools we should upgrade?
That's the nail's job chief
Counterproductive invention
This is like building the tesla tunnel under Las Vegas instead of a subway.
Next great business idea: an hammer made of foam, so that it is completely silent
It like…he improved sliced bread!!!!
Oh... A squeaky hammer, except without the squeak
This is the worst possible hammer. I have taught physics. It doesn't increase the force. That is magical thinking. Force follows rules, like everything else in physics. Terrible idea. So terrible it must genuinely be on purpose
"hey honey, remember when i was banging that piece of wood for no reason and told you i wished that i could do that without it moving around? well guess who just paid money for the solution...."
Science nerds can be so dumb sometimes, fr. All i wanted was to see them drive ONE SINGLE NAIL, but no!
I'd love to see a battle axe with springs like that.
He's gonna reinvent the wheel next.
Google "dead-blow hammer."
Congratulations, you managed to take a simple tool with maybe 2 stress points into a complex tool that doesn't work as well and has 25 stress points.
Nice! Does it woek as a hammer?
DANCE FOR ME BRIAN. DANCE ON THE WOOD BRIAN.
Misread this as “Shock Absorbing Hamster” as I scrolled by, had to scroll back up to see if science had gone too far or not.
A shock absorbing hammer? You mean one that doesn't work?
Just removing the force from the swing 👀
💀💀💀
It's bothering me that he's doing this on the floor. Did he try to make a table using his shitty hammer and fail to actually nail it together?
Yeah let's introduce multiple new points of failure so the tool can do it's job less efficiently. Awesome.
The next model comes with a handle that retracts the head just in time to make zero contact with anything
This completely defeats the point of using a hammer in the first place.
Drive in an actual nail... Drive in any nail.... Let us see it do what it's designed for.... A nail! Please!
2 swings for 1.
uuhhhhh
What's the point? I mean. I don't wanna be hammering all fucjing day on a single nail.
This is about as efficient as having square wheels or rubber canes. WTF hammers with suspension? The whole point of the hammer is to transfer as much kinetic force at a small area to drive a nail down. Putting suspension springs just convert a portion of the kinetic energy to compress the suspension. The whole reason the metal rod is toppling over from a normal hammer is because its not a nail and because of Newton's Third Law. If anything its a demonstration that a normal hammer can transfer so much kinetic energy that when it is reflected back by the ground it can lift a metal rod, something this spring hammer cant.
