Ok now make a coil spring from a katana

All these hateful comments about it not being a katana but can we just appreciate the time and effort he put into recording and making this for us? Have a nice day

I see a lot of comments that were posted within 2 hours. Looks like the youtube algorithm brought all of us here. :3

This dude is gonna end up making a tesla out of a toothbrush

Legend says he turn that katana back into a coil spring

From a coil spring. Bloody amazing, top craftsman!!

This is honnestly icredible! Good job! For those who don't know, katanas aren't made by only one person, there are lots of parts related to the process of making an actual katana. First you need to make the blade's steel which takes several days, shape the steel (japanese katanas take a process of shaping which envolves 1000 layers of the same steel on itself), polish the steel and then make the grip! All of this can take up to 3 months depending on the quality of the steel.

Bro i know it's not really look like kanata but i am appreciate your work because it's real forging not casting this is proof that this small kanata cut very well 👍

Roses are red ❤️ violets are blue💙 I got this in my recomended and you did too😵👍

Been working in Metal all my life never made a knife or any sort of blade thanks for the show it was interesting to see some thing so beautiful made out of nothing.

Definitely a good guy to have around in case of a zombie apocalypse!

Anyone else got this on their recommended?

Why is everyone bashing this guy? He acknowleged that this isn't a proper katana. Plus the skill taken to make a product like this from a coil spring is admirable. Well at least that's how i feel as a person that doesn't know anything about crafting or blacksmithing

Jake, the word what you looking for is wakizashi, the katans have at least 70 cm blade length 😉

Machete with Japanese resemblance. Nice and unique. Good job!

That's more of a Wakizashi than a Katana.

Best build I’ve EVER. seen, “good job”=understatement of the millennium. That thing is badass.

A beautiful job with mighty power

It's hard work you remind me of my father who passed his skills to us. Keep up the great work Respect. L.O.S.

I believe it's "technically" a wakizashi, but i could be wrong. Beautiful build, just gorgeous. I wish i was working right now so i could buy it

RU-vid really want me to watch this 🤙🏻🖖🏼👌🏻👉🏻🤟🏻🤞🏻

Bruh I’m not even into this stuff but I still clicked it . Came out clean as hell . Good stuff bro!

You sir are an inspiration. It'll take me two years and hundreds of tries to get something remotely similar to this. And probably a severed finger in the process.

He said himself that he knows this isn't really a katana. Way too short, among other many other things.. but that doesn't take away from it still turning out to be a badass looking sword. Forged from a coil spring, no less. Awesome!

more like a wakizashi, but yeah, great work~

While the neckbeards were busy studying the blade, this man was busy making the blade.

This is the type of content youtube was made for.

Closer to wakizashi, a katana is 80-120cm long. Also, the blade profile looks more like a chinise sword than a japanese one. But with those inaccuracies out of the way, It should be good at chopping wood and enemies alike.

I guess NASA can forget those launch pads. We got this dude's hands. We're set.

The sound it makes when he hits the metal is so satisfying.

Great watching you build ... would more call it a machete but it’s a bad ass machete

It’s more like a wakizashi than a katana, judging by its shorter length.

Someone please get this man some gloves! There's sparks everywhere!

thanks for recommending this, RU-vid

1 coil = 1 katana 1 spring = several katanas 😈😎 the stone was very tasteful. Well done

I wish I can have you as best friend during a zombie apocalipse.

Best thing that I've seen today. Making a sword out of common things. Recycle and reuse. Keep it up much love and respect👍

All I can say is WOW...!!!!!. Dude watching you doing what you do was relaxing. I enjoy seeing people use their creative minds and turn junk into something that can be used. As long as it's functional and can do the job it was created for. That's good enough for me. Screw the critic's. I wish you well in your endeavor.

Hello people from recomendation

Your so good of making sword...amazing

One of the coolest things I've seen on RU-vid

This is AWESOME. And EPIC.

Nice.... recommended after 2 years good job youtube😧😧😧

Love how nobody actually watched it and heard that he acknowledged its not a "Katana".

Long job and accurate. I love the swords. Amazing!

Outstanding! That is badass!

Dude that’s fantastic. Amazing work sir. Forget all these lame negative posters. Most have hardly touched a screwdriver.

He's ready for kill zombies now :)

I think it would look even cooler with a mirror finish!

This is the ultimate junkyard sword

i really dont understand what dislike for ?? this man spent time and hard work to turn some heavy equipment spear parts into a beautiful masterpiece i bet they cant do it, anyway nice job man it was my dad hobby to create some swards you remind me of my dad he may RIP . regards

Now forge a coil spring from a katana.

Very cool. Thank you for posting this video.

Appreciate your hardworking bro 👍🏻

a katana's curve doesnt happen by hammering. but from the difference hardness of metal in one blade and it curves when it is quench

Unquestionably cool, but also not a Katana or even a Wakizashi, in any sense of the word. A Katana is not a curved sword, A Katana is a specific type of sword of special properties attained through a long folding, and quenching process using Japanese steel called tamahagane. And the curve is not shaped by hand its done by applying varying layers of slurry and quenching to obtain different properties in the blade and the edge, the process of which gently causes the steel to pull itself into a natural cure. But it is a cool short sword. And you are undoubtedly a master craftsman in your own right.

You are the beast man.

Love this build, that sword is an amazing work of art, good on ya mate

Now forge a coio spring from a katana

LMAO I thought the guard was a piece of rock.

2017:no 2018:no 2019:let's recommend this

All with a Harbor Freight Anvil! Well done sir, well done.

Seems like everyone on YT read the same wikishitia page about katanas and believe they are experts on the topic. LOL no. Katanas were not a standard length. They were made to suit the height and arm length of the wielder, and mass-produced blades did come in different set lengths. Custom blades were made to suit. Katanas were not exclusively made from folding different metals like damascus; most were made from single alloy castings because of logistical and practical requirements. It is a myth that all "authentic" japanese katanas were of some mythical quality - most were relatively low grade because they were used to equip armies of expendable grunts. Only wealthy/high ranking officers and individuals got the good ones. Spring steel is already a good compromise between hardness and flexibility. This blade should hold an edge well without breaking if actually used. He never claimed it to be the best katana ever, nor did he claim any particular grade of quality. While a katana was generally a slender long sword, this does not qualify by being too short, but it fits the katana aesthetic. Machetes are made for chopping and have a heavier tip / light handle. This one seems more balanced, although he did not show its balance point (which he should have).

Even, yes not a real Katana, but hey did you see that what he make from those old scrap metal? I love to see, how some old scrap gizmo transform relatively usefull tool. Good work btw! :)

That blade looks nice! Great job 👍

Now this is a true man.

Hi Jake: I'm not gonna say anything negative. Because that doesn't help anyone and that's not who I am. Good job on the build of the sword and a congradulations on a video well done! Interesting choice of metal for the full tang. Coils springs have memory and whether you used a standard coil spring or a variable rate coil spring, the interesting factors of either can only be known under testing of the sword for cutting power on various materials...meat, bamboo, and possibly some cans of Campbell's soup cans for their thickness relative to skin or light body armor. Balance is another characteristic worth looking into both for the draw and under weilding of the sword! The tsuba however, while well made and original in material and design. It did appear to be a bit too small to provide protection by a glancing cut by an attacker! The handle length is also too short to be held by two hands and weilded for specific cuts and blows! It is important that the full tang not fracture nor develop fractures nor shatter under a collision or contact by another sword or object. Overall Great job!

9:11 clean cut😂

That saw you got sounds like a radio broadcast mixed with an anime powerup.

Jake 4 forged in fire!

Я так понял, у всех только что в рекомендациях это видео вылезло

Of course, all the white collars criticizing the work here, have already forged a sword, or a knife :-) Even if this is not a katana, it is a nice piece of work, well made without hesitating and using crap iron. When you'll have tried forging something, maybe you'll understand how tricky and difficult it is, and you will pay more respect to the work of the others.

very impressive Thank you for the video great job

You sir are a true smith!

The fuck? I just read people insulting this work, but I don't see anyone doing it better. It might not be a Katana, but still is an amazing work. Keep it up dude, it's a cool talent.

No one : Not even a dog: RU-vid: wanna see a man carve a katana out of a coil spring

Very nice. Uniqueness is key in this build. The guard and pommel are what makes this special in my opinion. Subbed.

Stunning.

The negligence of safety horrified me

Legendary smithing Skyrim. 😂.

Respect to your creativity. Nice video !

simply the best

2017:not yet 2018:maybe 2019:yes wanna watch this? Here I'll put it in ur recommendations
