my heart cries.. this is end of a noble katana.

It's a beautiful iron rod. 綺麗な鉄の棒ですね。

戦後、米軍に持ち去られた刀（蛍丸など）がこんな保存をされて、こんな風に扱われているなら悲しいことだ。

ホイキー観た後にこれを観ると泣けてくる

残念以外の言葉を　見つけることは出来ない。 みるも、無残な事になってしまった様です。 あの当初の歪みからは、焼身の可能性は否定出来ないとも思われますが、日本刀の修復は、この様な技術では出来ない事は、明白です。

ガーガー削られてるのを見て想像以上に心が痛んだ

動画冒頭で、日本刀に特有の刀身の反りがあまり無いことから、おそらく火災に遭遇した刀身と推測しました。つまり最低限の復元でさえ、本当に詳しい鍛冶師でなければ不可能でした。 温度の不安定な焚き火で焼いたことで、反りがさらに減っています。これは鋼の質が落ち、硬い刃物ではなく形を保てないほど柔らかい鉄板になった明確な証拠です。 最後のペットボトルカットですが、本物の日本刀ならばボトル下部は台座に残ります。これはそれだけ鋭利に切る、そして切る以外の圧力を与えないことを示します。台座から吹き飛ぶのは、切るではなく押しのける力が発生しています。 本当に、本当に残念ですが、この刀は日本刀としては死んでしまったようです。

あなたの努力と復活させたい気持ちを否定するつもりは有りませんが、日本人としてとても悲しくなる動画でした。多分、日本人の多くの人が、心を痛めたと思いますよ。

努力は認めますが、これはもう日本刀と呼べる代物ではありません… 見ていて心が痛みます…😭

ただの鉄の棒やな😂 とても日本の刀とは違う物になってしまっている😢 めちゃくちゃですね😂

火に入れたらそれはもう日本刀ではないよ…。 それに磨いてるのはサンドペーパーでしょ？ ここまで来るともう復元ではなく破壊に近いよ。

😅ペイパー研ぐなんて❗ 砥石で研がないとまともに切れない😅

いや、日本の本物の刀鍛冶はこんななおし方しませんからw

こんなの復元じゃない・・・頼むからもっと勉強してからやってくれ

I think the blade is not a katana blade.It looks like a cavalry saber.That gives me comfort to know that no Japanese sword should ever be treated with such disregard.

復元とは言い難い、寧ろ刀を殺している

Thus, the Japanese Katana became a mere iron sword...

日本刀の事をもっと調べるべき

栄光と力の帰還と称して、全力で刀を只の鉄の棒にぶっ壊していくスタイル、、、、 錆落としまではギリギリなんとかなったかもだけど、火にかけてヤスリにかけた所で致命的だぁ 何かの職人さん何だろうけど酷すぎるな、最低限勉強して欲しい、、、

外国に砥石が無いことが残念です

Looks like a KATANA sword to me.

日本刀ではなく、単に特大のナイフになりましたね

片刃のようですね。残念ながこれは日本刀ではなく、マグロなどを解体する包丁だろうと思われます。 以前、東京の築地市場でこの包丁を見たことがあります。 日本刀は両刃です。お間違えのないようにお願いします。 それにしても、荒っぽい復元ですなぁ !!

これは日本刀の破壊行為です。 本来の修復工程からかけ離れています。 伝統技術で直せないなら、錆びたままの方が価値があります。

Парень, ты убийца мечей! Зонная закалка тем и хороша, что клинок свободно рихтуется на холодную. Но рихтуется без ударов. Ни в коем случае нельзя было греть клинок. Такие клинки калятся только один раз. Спуски сведены, и тонкая кромка при нагреве, теряет весь углерод. В общем на это больно смотреть.....

期待してなかったけど予想通り模造刀づくりだったな。日本刀の復元って書かないでほしいな。

サビ取り・磨くのもいいけど、やっぱ技術が必要だしプロに頼むとかになるけど再度焼き入れて叩き直した方が良さそうな気がする

鈍刀になったのは理解出来ました

Not a real sword (katana), but the job you did to bring it back to good condition is was very well done. I applaud your work. Well done.

日本刀の復元ではない、破壊 栄光は帰還していない、むしろこの作業で殺された 残念でしかない

焼き入れはバーベキュウじゃあ無い！

It's not a katana.

The way an authentic katana is made it wouldn’t bend

A work of Art.

That blade you pulled out of the solution was suspiciously free of rust pitting.

I read these comments and am trying to understand your history, pride & disappointment in this sword being treated so. I also thought of your initial Ancestral Katana makers and the years it took to create one blade. The power tools used for the restoration had me realize how long just drilling a hole or any slot opening in metal, hammering the layers of steel that had to be made, etc. Please reply why this isn't correct so you can educate me. Many thanks...

Блин, ну с рукоятью накосячил, моё почтение. Обмотка шнуром на отъ...сь. бляшек "менукэ" нет. С цубой, то-же косяк на косяке. На цубе катаны, должно быть два отверстия, для малого ножа, и "швайки". Для развызывания шнуров. Нож и "щвайка", соответственно в пазах ножен. Нож с наружи, "швайка" внутри.

日本人が作った世界最高傑作の日本刀を、見よう見まねで鈍らにしている。 温度管理もできない外国人に日本刀は修理できない。 まして研ぎの技術を持たない人に刀剣の美しい波紋を再現できることなど到底皆無である。 この程度の模造品を賞賛するなど日本の伝統を傷つけたことに怒りを覚える。

これは日本刀ではないです。 ただのナイフです。 このようなナイフが日本刀（NIHONTOU)として世界中に発信されたのでは、見た人は誤った情報を信じてしまいます。 本物の日本刀が泣いています。 作者は日本に来て、本物の日本刀の作り方を勉強してください。 This is not a Japanese sword(NIHONTOU). It's just a knife. If such knives were disseminated to the world as Japanese swords (NIHONTOU), people who saw them would believe the wrong information. A real Japanese sword is crying. The author should come to Japan and study how to make a real Japanese sword.

Если это настоящий катана ,то жаль катану!

Amazing! But I am curious. What does the coffee do for the blade?

How long did it take you get the rust cakes on like that

The sword blade, which had rust removed by a rough process, showed a good figure and ground surface. The act of scraping rust off the stem and blushing the sword blade with high heat is a ruinous and barbaric act against Japanese swords. A valuable cultural asset was lost in front of my eyes through ignorant torture.

Nice resto but this is a mass produced sword made for the lower ranks, genuine katanas were reserved for the officer class who often carried family katanas which often were priceless relics hundreds of years old.

Nice wall hanger, if you tried to strike something hard with it the handle would probably snap in half, since the tang is only half-length.

This is how a katana is not restored originally

As a Japanese person, I cannot recognize this as a Katana.

Silently restoring, not a word can be spoken!

I enjoyed your video very very much keep I would like to see

You have patience and skill and as a result a fine knife is being reborn.

So - Hatori Hanzo lives! Here's a tip. Next time you might find even thicker plate for the Tsuba, find a scrap manhole cover - those can be up to 3/4 inches thick. Nice way to find an alternative use for firewood in the Tsuka BTW, PLUS - you noted how the Japanese never got the Mekugi material right, and inventively used -was it steel instead? Aluminium? Nice work, bro.... 😢😢😢

昔古来より伝統ある日本刀が間違いだらけの復刻されているのを見て心が傷みました。

Mantab jdi baru 👍

so this is why haganezuka wants to kill tanjiro evertime he broke his sword....😂 its pain in the ass to restorate the sword...😂

I can only hope it was a cheap WW2 blade

take too much metal off, the blade will be thin and weak if inner core is exposed....this katana looks to be severely rusted...however, is that rust or a coating that is being removed?

Que pena, nenhum produto ou material, foi citado para que, e como funciona 😢

Where did you find the sword? What is the story behind it? Nice work. Was the cutting test done before you o=polished and sharpened it?

Những thanh kiếm ntn mới gọi là kiếm đúng từ tốt hồi xưa các chiến binh sử dụng

Nice job

Turned out lookin' hella dope, SkillFullisM!

Well Done 👍

模造刀をリペアした動画。

OMG, Good work, and than this red silk ribbon!!!😢

Я думал, что на моем дедовском молотке рукоять как черенок от лопаты выглядит, однако по сравнению с этой катаной молоток произведение искусства🤣

Thank God that wasn't a real sword. 😂

Такой инструмент, изуродовал лишенец

Những thanh kiếm này nó thực sự cả một gia tài chứ không phải đùa

and who has the experience, what is the right colour for the material the blade is made of?

これは復元ではなく、破壊ですね( ﾉД`)ｼｸｼｸ…

What does the boiled coffee do?

👍👍👍

これは模造刀でしょうか本物の日本刀は玉鋼を何枚も折り重ねて鍛錬したものですからこのような腐食の仕方にはならないと思いますし所有した方は保管も丁寧なはずです．柄の拵えも作り方が全然違いますね三流映画の小道具のようです（笑）

Great job."

Вместо закалки за воронил . Потом сам же стер воронение наждачкой :) Линия хамона не получилась . Нельзя сказать чтобы не пытался :) Может ее проще было бы сымитировать? Например воронилкой покарасить лезвие , и оставить кромку лезвия не крашеной

Как только сунул его в печь, меч на этом закончился, его калят в первый раз - он же и последний. Похоже, умелец не в курсе, что холодной рихтовке поддаётся и закаленное изделие. Например, длинные закаленные и отпущенные свёрла из быстрореза рихтуют перед шлифовкой. Это я видел на инструментальном заводе и тогда удивился, что это возможно. Потом и сам рихтовал заготовки ножей, после шлифовки их нередко ведёт.

こうやって　模造刀の劣化品がネットに出回るのかー

That length looks more like a wakizashi than a katana.

So Which is it A Samurai Katana or a Ninjato

Isso aí parceiro, show de bola Att: Weliton Marks - Canal Desbravatube

これ本物の日本刀じゃなくて見様見真似で作られたスプリング刀っぽいね模造刀ですらない 横の歪みはともかく縦の歪みが不自然過ぎるし茎の作りが非常に雑

Try die maker stones of various grits. Gesswein makes good stones. Use with WD40. Your life will change. Nice work!

You retemperd, it's not the same sword . Nice work with metal, did you test it.?

I can only hope that this was ether A. A cheap knockoff katana or B. A relic found on a field from ww2. Because I am a martial artist and a practitioner of the way of the katana. For someone to willingly and knowingly let there Katana get to the state it was in the beginning of this video is an outrage. If you can’t or don’t know how to care for the sword don’t own it. In Japanese belief the katana is the heart and soul of the samurai it was cared for above everything else in a samurai’s life and was with him till his death. It’s great you brought this one back I hope you won’t let it get to that condition in the future.

It must be mass produced factory replica. No marking or makers mark engraved on the handle. I don't think its that old either there was practically no pitting on the blade after first clean. Good effort though.

Hi .why did you put that sword under heat to straighten it? :-

not sure about the desire behind this video, and what factors went into the completed project. but, when you do work on cultural pieces outside of your own, you do need to do a fair amount of research so the viewers can see that you at least made an effort to do things correctly. some here were saying basically that effort was made, but i can see that the work was done with more of an "i saw it in movies" kind of thing, verses "i did a few days of research and did my best with the materials i could afford" kind of thing. how the (ray skin) was applied, and then the wrapping shows just how little thought he put into it. it looked like how i did it when i was a kid trying to make a samurai sword...which was okay by a child's standard. i've seen knives being restored, and made, with much more thought. all this together shows he doesnt really understand that japanese swords are prized possessions, instead of just something a metal worker thought would tickle his fancy. by his standard, it probably came out very good, which i respect. but, he broke a lot of hearts working on something more sacred than he realizes. take it with a grain of salt. we've all been there wanting to try something. props for that, of course. but, it is valuable to do more research about things you have little to no experience in. looking at his effort, and ability, you can tell he can create a much better result. perhaps, he just didn't have the time. just a note. perhaps he knows the blade is not authentic, so he treated it that way. as far as polishing to mirror finish goes, it's extremely important, as doing so better seals the surface against oxidation. so, yes, fine polishing is important in the life value of a fine piece.

i am supprised that there were no markings on the sword as to tell which master made it or an indication of its histroy.

What a half assed job. You did "OK" about half the way thru the blade resto but then turned armature. That short tang will split the handle the first time you use it. You could have used some nicer material for the hardware. and then what did you wrap it with...looked like chap ribbon. So sad, this blade could have been turned into a work of art. What a waste.

Yeah! A real Japanese sword smith, would turn in his own grave!

Polisher of souls! Nice job on an ordinary old Katana.

A real katana sword are indeed extremely expensive $$$$$$; no person in their right mind would let a very valuable sword to go to waste.

これ持って、山の開拓にでも行くんか？

Катана с ребром жосткости первый раз вижу

これって、スプリング刀ですよね、外国人が見ると日本刀に見えるんでしょうね。第二次世界大戦の戦時中に作られた模造品 明らかにおもちゃですね。日本刀の神髄は焼きと研ぎにある。

а где линия хамон (линия зонной закалки на традиционном японском холодном оружии)? на мече самурая всегда такая должна быть!!!

作業している方は本当に日本刀の性質を理解していませんね！単なる旋盤工さんですね！

Não seu nada sobre armas,mas .. parece que vai ficar uma jóia MAGNIFICA. Parabéns 👏👏👏 SUCESSO SEMPRE 👏🎇🎇👏🎇🎇🎇👏👏👏

It's probably not an official way to regenerate a Japanese sword.

It is no longer a real Japanese sword, it is not a sword at all, but just a long knife with an inexplicably tempered blade. By the way, it was most likely a Shin Gunto from the beginning
