Be sure to vote for me in the Epilog contest. Cutting shapes out of card is pain, so I need a laser to do it for me!

I have owned a set of samurai swords for a short while now. They sit nicely on my shelf, and are a great display piece. I however wanted something unique. There are two ways to get unique-

1. Spend alot of money on getting a custom item built.
2. Build one yourself.

I opted for the latter.

I have never done any metal work in my life, so I chose to buy a cheap blade, then recycle that into my own sword. I faced a problem here, as I wanted my sword to be purely decoration, something someone can pick up and enjoy its aesthetics, but unable to cause major harm, I purchased the sword of ebay, but i struggled to find a listing with a 'non sharp' blade, most buyers ignored my questions.

Finally i found one, a shortish sword, straight, one sided, pretty much what i was looking for.


The Liquid Blade of the Three Deserts is made up from a poly-bicubit liquid metal held in place with gravitational magnetic fields. Based on the 'Melon sword' concept, the magnets hold the liquid in an impossibly thin alignment, spanning only a few atoms wide on the sharp edge. A small reserve of liquid metal in the handle allows loss and healing of the blade.

The blade is given extra functionality with the spear tip located on the scabbard. When sheathed the sword can be used as a lunging spear. It also then doubles up as a two handed weapon, sword in one hand, spear tipped scabbard in the other.

Located in the handle is a gravity modifier, this has several purposes, the first is regulate the blade, and hold it in place. Second is to provide a perfect balanced blade no matter what stance, or how the blade is held. Finally, it can be clocked into over drive to deliver a 37 fold blow.

The name of the blade comes from when the overclock feature was first tested, the sword was ramped up to full power, and one brave individual strode out into the test zone, a swift swing brought the sword down onto the desert floor, only to crack the entire coastal region into three, creating The Three Deserts.

Mmmmm... Three desserts... Nice work :)
This thing looks so cool! a especially like the hilt! very nice design. 5 stars!

Puttin the leather into warm water before using it, makes it more bendable and lowers the risk to rip it on the bent edges.

Best solution to glue it, imho, is to use the leather workers' glue. After drying (you have to put it on both glueing parts) it sticks like hell, which might make it easer to tear it around edges
by the way sorry for the rant 2 years after you made this weapon. i think it looks awesome and it inspired me to recreate my own hilt and scabbard. but take it a step further and make it out of wood.

Its ok, you are allowed to rant, but did you try googling 'Melon Sword' The entire epilog was made up, using my imagination. Including the fake science.

Like all great science fiction, I made it up to add a false realism to the idea.
Which you managed to fall for in spewing out that rant.

Thanks for the compliments, I would very much like to see your variation if you can spare a few pictures.

Try not to get to het up about things, it is just the internet, its mostly for fun.
lol i know it was all made up. im not trying to say it was based off anything. i was merely stating that fact that you are allowed to have an imagination.

"Based on the 'Melon sword' concept, the magnets hold the liquid in an impossibly thin alignment, spanning only a few atoms wide on the sharp edge." Actually, a well-sharpened blade is often only an atom or so wide at the edge. Still it's a nice sword, and I especially like the spear point.
gmjhowe (author)  WurdBendur6 years ago
Actually, a well-sharpened blade is several thousand atoms wide at the edge. You can never actually get a one atom cutting edge due to the weak force. The single atoms simple fall into a more stable position onto the atoms below.
Ah, I guess you're right, but a few atoms wide is still not impossibly sharp.
gmjhowe (author)  WurdBendur6 years ago
With todays technology it is.
First of all, edges tend to be rounded, so saying how thick they are doesn't make much sense. Thick where? How far back are you measuring? I could have a blade about as sharp as a basketball, and technically, if I measure in the right place, the edge will be about 1 atom thick... That's not a useful means of quantification. What is used instead usually is edge radius. And diamond blades are made with a radius of about 10 nanometers. Given that a CC bond length is about 150 pm, that would be approximately 70 atoms. I'm sure experimental ones have been made smaller than that, and this is a radius, remember, not the width of the absolute tip of anything. It gradually ramps up from 1 or 2 to 70 over the course of the edge's roundness. I have no idea how that translates to your pretend sword, because you're not using standard measurements. Also, no matter how sharp your sword is, it wouldn't be that much more useful than normal sharp sword, because you still have to have the strength to wedge two sides of an object apart up to the WIDEST part of your sword. If I want to cleave a boulder, I have to have the striking strength to peel apart the rock the entire width of the BACK of the sword. Which would be hard enough with just inertia to overcome, but add in the fact that the front of the boulder is still intact, and now we are talking about BENDING the boulder outward with just my arm muscles. Not going to happen. Sharpness doesn't really do that much for you after a point. Much more problematic, however, is your whole "overclocking" thing. Overclocking a field that holds material in a certain shape would do nothing more than hold the material in that shape even more securely... It would not in any way lend extra force to any blow.

Yeah, thanks for your comments, but its sci-fi. Science Fiction. Google that last word if you wish! It only has to have rough groundings. The 'idea' of the sword is merely fantasy loosely based on science. The discussion that began on this thread was merely two creative people musing of the workings of such a sword. Before you interjected it with science, simultaneously destroying all creative outcome.
Okay... From wikipedia (may as well use that, it's not exactly empirical): "(Science fiction) differs from fantasy in that, within the context of the story, its imaginary elements are largely possible within scientifically-established or scientifically-postulated laws of nature (though some elements in a story might still be pure imaginative speculation). Exploring the consequences of such differences is the traditional purpose of science fiction, making it a 'literature of ideas.'" Yeah, some of it is tantamount to magic, but it's traditional to still "explain" such events in terms of some kind of unknown technology that makes sense. Splitting a geographical feature into three pieces is something that needs a lot of explaining. For instance, the postulation of mythical elements that have a near infinite capacitance potential, etc. I'm not like disgruntled or anything. I'm just constructively suggesting good storytelling practices - there are certain rules of thumb which have been perfected by the sci-fi community to ENHANCE the impact of creativity, not destroy it at all. The best and most creative sci-fi stories don't just lay out unbelievable things with no plausible explanation of any kind; it makes for a less engaging story that is harder to get lost in. Instead, they explain things in plausible ways. Star Wars has it's midi-chlorians, Dune has reasonable backstories for pretty much every tiny thing out of the ordinary you can think of, Asimov based all of his stories pretty much on realistically achievable future technologies (another route), etc. Are you claiming that all of these productions lack any creativity??
About star wars....do you really think a lightsaber applys to your arguement??? Exactly so why not just let these guys do what they wanna do and lighten up?
Lightsabers are just energy swords. What is there to explain about them? They have some sort of crystal that focuses energy like a laser in phase (which is indeed discussed), and that allows you to cut through stuff in the same way as a laser does. They don't slice mountains in half or create hailstorms. They just cut stuff (often very slowly, at that - not really any faster than a real life thermal lance for big metal doors), and it's fairly believable. Also, if you'll notice, I never complained about the part of the instructable where he says a field holds the sharp edge of the sword, which is the equivalent to a lightsaber, and which he DID explain. I complained about the much bolder "it split a desert into three parts," which needed a lot more explanation and had none. I also complained, because in addition to being unexplained, the "supercharge" notion actually contradicts the field that holds an edge. As I said originally, it stands to reason that if you supercharge a shape holding field, it will just hold a shape more tightly. Claiming that the sword gets more power instead is confusing and seems like you baited and switched us about what the sword actually does. It feels like a prop department mistake, almost (like that scene in deliverance where they shoot the guy with a rifle, and he has an arrow in his back later). The narrative is broken, it feels campy, and it's just poor practice. Nor can I think of a single example in famous sci-fi pieces where something similar is done. (Lack of explanation, yes, that happens, but still infrequently.)
oki do you have any imagination at all dude for all we know the liquid sword could be made tom. and further more look at the definition of si-fi again. look at the things that EVERYONE IN THE WORLD puts in that category. I will list some of the things for you: anime ( which lol by your terms of def. to science fiction is impossible) light sabers ( which yes are lasers but still haven't been fully developed yet), cyborgs( which yes by true science they can exist but still by your def. don't) zombies( which again don't truly exist yet but still possible). those are just some of the things that are under science fiction. So you saying that oh the liquid blade could never exist out of science fiction nor in science fiction is irrelevant, why? BECAUSE IT IS MADE UP!! i mere thought up story behind why the sword was made and how. It doesn't matter if it is based off of some sort of realistic concept. Ill give you another very very good example. The rail gun, I'll bet that 50 to 100 years ago if you went to the military and said hey i have this idea for a gun that shoot a magnetically powered piece of metal at an object past the speed of light and sound using electromagnetism they would either throw you in jail or killed you for being a spy. so that ends my rant on little ignorant people that have no imagination. thank you and have a nice night.
If this is all you do for your day. You need to get a life. It is make believe for a reason. Use your brain and think "outside the box"
gmjhowe (author)  smurfsahoy6 years ago
No, I'm claiming that your taking things way too seriously.. I never said anything about the sci-fi community destroying creativity, that was purely aimed at yourself. If you really want to think up a scientifically correct version of how it all works, then feel free. Personally, I like to think up original ideas, that are way out of line with our current understanding of science. You mention great authors like Asimov, whom at the time, his ideas were way beyond any actual scientific understanding, and still are today. Thats what makes him great, the fact that even today, his ideas still seem like they are in our future. Think outside the box my friend.
NERD FIGHT!!! >Ducks flying pocket protectors and headgear<
gmjhowe (author)  Lithium Rain6 years ago
Nah, fight implies he has a chance of winning.
Well played.
Edits: 1) The 70 atoms thing is obviously not strictly correct, since the atoms are not lined up in a row, but it's a good rough guess. 2) I have no problem with whimsical creativity or fantasy swords or whatever. But I think that you should either just say it's magic and be done with it, OR you should actually have the science make sense. Pretending something is completely grounded in real world science, but then making claims that don't add up, seems contradictory?

i have a katana that's around a half centimetre in width, so i think that the cardboard is'nt a great material here, it is also curved upwards like the traditional ones, so mine requires a lot more work, but still, i love all of your works ive seen so far, especially the steampunk guns
Xankahr4 years ago
I defiantly did my own project based on this, you'res is awesome, i made mine using basswood for the handle

Very nice to see such good Craftsmanship.
Get up the good work!

hmm, i have been looking at buying this sword, you say it's good quality? could it be sharpened with a file/grinder? (to a machete kind of sharp or better)
gmjhowe (author)  Neovenetar5 years ago
As far as I understand, the metal is not designed to be sharpened, that does not mean it can not be. I have never tried, as I did not want to ruin the finish (you may have to refinish it or something)
did it come with a handgaurd or was just as it is with a wrapped handle?
Neovenetar5 years ago
have you actually used this sword to cut anything, or is it just for show?
gmjhowe (author)  Neovenetar5 years ago
I specifically got an unsharpened sword, as I wanted it mainly for show.
hm i guess that explains this: I VILL KILL YOU ALL WIZ MY TINFOIL SPEAR!!!!!

I like the idea of a sword still being deadly while it's in it's sheath, but,.....this thing is essentially just cardboard, with a sword somewhere in the middle of it. Also, I don't know where you got the idea for this thing's backstory, but the 'gravity wheel' makes it look like the blade can fold at the handle.
JamesTB135 years ago
That is some funny-looking cardboard, what the hell is it? Usually cardboard is two pieces with a zig-zagging piece inside, sooo.........what the hell do you have?

heys yous saids yous woulds nevers makes somethings thats woulds hurts peoples buts cools anys ways ...whats ares thes three desserts anyways
gmjhowe (author)  Articas6 years ago
If you notice in my description, i had not end of trouble specifically hunting down a blunt blade.

The three deserts is explained in the epilog in the first step!

Its also an underground group of elite assassins... but i didn't tell you that...
I found out what the little tiny text says! :D Its also an underground group of elite assassins... but i didn't tell you that...
No matter how blunt the blade is, you can still split someone's head open if you swing it at full force, heck, at the very least, you can even bludgeon people to death using it.....
gmjhowe (author)  Camisado6 years ago
But at that point, the same could be said for any long metal object. Everything is a weapon.
Well, that's true, I'm just trying to say that no matter how blunt your blade is, you can at the very least use it as a bludgeon. (Which, IMO, is a good thing :-P)
lol! What a parody on it. The liquid blade of the three desserts. I can see it now. A jelly blade with a handle made from cake and a pommel stone of biscuit!
