The sharpest Japanese sword ever. It takes some skills to use it

日本刀と聞いて見に来たら包丁研いでるだけだった……

The guy in the back

😂😂😂the hell

日本刀じゃなくて普通の包丁な。

なぜ砥石の上に砥石を重ねていくのか？

Skill is needed. You can give that first guy back the knife and still won’t get same result.

最初から研いどけよ。

Is this the samurai sword?

Yes indeed

日本人はこうやって縁日とかで実演販売するイメージ 一枚が二枚。二枚は四枚。四枚は八枚。八枚は十六枚。十六枚が三十と二枚。 三十と二枚が六十と四枚。六十と四枚が一束いっそくと二十八ふたじゅうはち枚。 とか口上で売るのはガマの油という軟膏。

どこの国の刃物でも研げば切れ味増すよね…？

Maybe we should have sharpened it before the video!

研ぐ時、刃を立てすぎてる気がする もっと寝かせて研ぐように習った

The first guy didn't cut through because the blade wasn't sharp. He just didn't swing hard enough. The failed cut is due to the drag of the blade sides in contact with the mellon peel, not the cutting edge. Same reason why cutting cheese is difficult with a wide blade.

the irony is that traditional japanese folding wasn't magic metallurgy; it was an ingenious workaround for inconsistent bloomery steel. the craftsmanship is impressive precisely because the inputs weren't.

最初の人力入れてないじゃん

Lie and deception. As shown in the video, the knife CANNOT be properly sharpened. In addition, the force of the swing with a "sharpened" knife was much higher than with an unsharpened one. A video for the naive and ignorant.

日本刀ではありません 日本の包丁の一種です

the build up on this with the sharpening left me wondering what would happen next

@FimsonJ

包丁やん

So he gave it to the first guy super dull and now we're supposed to be impressed?

Why aren't bullets & missiles sharp discs? #MyInvention

Rubbish, look where the first man tried the cut, near stem which is the "thickest" part, where as other guy cuts near mid top, thinner skin/flesh..

Not the sharpest and not a sword

その赤い服なんなん？ 研ぎも下手 石がグラグラしてない？ 幅うすくない？

That’s not a sword nor a katana.

I would never eat at a restaurant named Mohamed.

切先が日本刀のそれとは違うように見える。

All the shit that the Jap would do to cut a watermelon Dress up, sharpen the knife... While a normal knife can do it Actually the fact is that watermelon is pretty expensive in Japan and they need a ceremony for it

横に切るのは技術が必要なので縦に切ると簡単です
