Happy new year I was afraid of hydrogen and the work did not proceed, 水素恐怖症になりました。怖すぎる

this guy is the definition of the saying "if you want to make a pie from scratch, first you have to make the universe" but for knives

休止したのかと思ったら、6ヶ月も不審なことしてたとは...(最高すぎる)

You know something that people don’t appreciate about this guy enough? His cinematography. Make no mistake, this is a display of chemical wizardry and blade crafting of the highest caliber, but the clean camera shots, balanced spacing, and crisp timing, plus the hours of editing that must go into creating these videos are just as important. Edit: grammar

この人の半年間がこうやって20分に凝縮されてると思うとすげえ

長い制作期間だから生きているのか心配やったけど、さすがのクオリティやわ

なんだろう…この人の動画の前半何してるか全く分からないのに包丁研ぎだした瞬間に実家に帰ったような安心感が…

this guy puts more world building and lore into a video about making a knife than like 70% of tv shows i've watched

期間的にそろそろ新しい動画来そうな気がするな… また１から素材を作って包丁を研いでんだ絶対

It wasn’t until 18:15 that I remembered “Oh yeah! He was making a knife!” I got so caught up in just watching this alchemy.

生きているかどうか心配してる間にこのクオリティ作れるのマジでリスペクト

もはや包丁作るのを見る動画というよりよくわからない実験を見る動画になっている

今はどんな変態的なもの作ってるんだろうな...楽しみすぎて夜しか眠れねえぜ

More edit: OK I get it now, the Satanic ritual was NOT for the candle, it was just for fun. When the ritual failed because the candle broke, the Grim Reaper stepped in and hooked Kiwami up with some raw materials; this was unrelated to the ritual, the Reaper was just a subscriber/fan. As always, this is just my best guess. 1. Oil extraction from rice bran: To make wax, he is making oil. They're closely related cousins. To get oil, he needs to ask the Grim Reaper for his latest fresh harvest: raw rice with husks still on them. The vegetable oil is in this husk. - Crush up the rice + the husk into a mix - Mash them, boil them, now all the oil is taken outside of the husk and into the liquid, along with other impurities - Let the liquid air dry, leaving all the chemicals - See how this brown chemical isn't mixing with water? Because this is mostly bran oils - Mix it in water, the oil gets a bit emulsified, impurities dissolve into the water - Let it sit so the oil we want floats on top - Now we extract it by getting rid of the water slowly using this filter device made from boba straws and a funnel. - Wash it in an alkaline (high pH) solution so that more impurities dissolve out, leaving the oil. - Centrifuge device = the doll with the spinning head in the bath tub. Fun for the whole family. Anyways, the heavy liquid gets flung into the bottom, while the lighter bran oil stays on top. This is to show you the product is indeed oil. - He cooks the rest of the oily liquid in the beaker. Now that the liquid dried off, what we have left is oil. Oil is amphipathic = it is a long string with one end liking water (hydrophilic) one end hating water (hydrophobic). Amphipathic = soap. Why? Soap is used to wash away things that water cannot, like oil and dirt. You wash your hand by filling it with soap, then rinse off with water. Soap will grab onto the dirt on its water-hating end, then its water-loving other end will follow the rinse water and now your hand is clean of dirt. 2. Hydrogenation of oil: - Think of oil as tiny, tiny microscopic wood. Now oil has 2 kinds: saturated or unsaturated. Saturated = oil is long, thin, stacks very nicely, imagine a 100 planks of wood stacked on each other. Saturated = unhealthy oil, because just like that stack of planks, this oil will stack together and solidify, it will look like butter, animal fat, margarine, etc. Unsaturated = healthy oil, these strings do not play well and do not stack, because they have double bonds poking around. Imagine if your wood were not planks, but branches. Branches don't stack well. - Right now we have vegetable oil = unsaturated = liquidy oil = NOT wax. - Now we try to remove the double bonds by adding Hydrogens = Hydrogenation - To make Hydrogen: mix magnesium with citric acid = Hydrogen gas (H2). See how it fills up the balloon. Yes, this is Hindenburg gas. 9:07 see how it burns off very quickly. If he had a bigger balloon, it will make an explosion. - Catalytic converter = source of Pt, Pd metals. This is catalytic metal for the hydrogenation reaction. - Diethyl ether = water-hating solution to dissolve oil in. Like dissolves like, so water-hating oil will dissolve in water-hating diethyl ether. You need to dissolve oil to make the reaction go FAST. - Pressure chamber: not to sure TBH. I think he is using pressure to force the H2 gas into the dissolved oil + metal solution, making the reaction go. - Cook it in the pan: to let ethyl ether evaporate off, leaving the now saturated(sat) oil. That's why you see the oil solidify quickly. 3. Making wax: - Add the sat oil into water + salt. Salt = NaCl. New edit: I think this was a Pickering emulsion. Salt + oil in water will stabilize the oil into fine droplets and not blob up. He then washed the salt off the oil. - Add acid into the oil. 1.5 pH acid is probably HCl ? - Esterification of fatty acid with an acid catalyst. Or maybe it is transesterification, I'm not sure. There should be an alcohol or glycerol here, maybe I missed something. - Ester fatty acid = wax. Finally. - See this thick yellow thing? Wax - Doll bath tub/fountain: this is a distillation setup. Basically forcing all water to evaporate out. - Dryer (?) fan: probably to dry out water. - Brown stuff = concentrated wax. 4. Making knife: - Handle is made from regular candle wax with some color, oh and also used Barbie's body as a mold. - Blade is made from the concentrated, hard wax. Now you can have an affordable and sustainable Satanic ritual: burn candles AND stab the victim using an all-in-one knife candle. PS: OK usually I just explain the science behind the knife making but after the ritual in the intro I had to consult with the local Satanic Temple, who responded, and I paraphrase, no, they have no idea what unholy sorcery Kiwami is cooking up to make the knife. So I guess I'm on my own again.

I feel like this is no longer about knife making. Its more of an experience. No questions asked, just watch, and be amazed

なんとなくどんな反応が起こってるか考察してみた。 7:34までは、米糠から油を取り出して精製する過程だと思われる。 そこに水酸化ナトリウム溶液を加えて油脂と水酸化ナトリウムのエステル化で石鹸ができる。 13:10までは、油に白金触媒下で水素付加することで油の多重結合を切り離して単結合にし、飽和脂肪酸を増やすことで常温で固体の油脂であるマーガリンを作った。 14:45までは、石鹸水に塩化ナトリウム水溶液を大量に加えることで塩析を起こし、石鹸の分子を析出させることで石鹸を精製していると思われる。 15:58までは、精製した石鹸の溶液に酸を加えることで石鹸の3つのNaの部分がHに置換されて、蝋燭のロウである脂肪酸を取り出す事ができた。 全部高校の有機化学で習う範囲だけど、それを実際に活かせるのマジでヤバすぎる…

長い間動画投稿がなくても不安にならないチャンネル·····むしろ期待が膨らむ😌

Finally, our retired chemistry professor who has been arrested because of murderous crime and escaped by making a katana with toilet paper is back.

米ぬかからロウソク作るってのも大概だけど、それ以上に半年掛けて作った包丁をなんのためらいもなく火をつけて溶かしちゃうところが物凄い。 さすが不審者の極み様！！狂気っぷりが半端ないです！！

this is pure zen artistry, as both a bladesmith and a chemist I'm in awe of the work that goes into this, and the respect for the work knowing it will be destroyed at the end.

遂に捕まったのか

I have the utmost respect for this guy. It took him 6 months to MAKE enough material to make a candle knife, and he still lit it up on fire despite it ruining his creation.

I love the fact that at no point during that entire video, did I know when he had actually made the substance he was trying to make

これがオススメに出てきてそろそろかと思って来てみたがまだまだだった

とりあえず液状になれば何でも包丁にできると思っている男

this channel is literally mesmerizing. it’s not the floating beheaded doll that freaks me out, nor the exorcist doll in a rose bathtub. it’s the sudden introduction of margarine, after minutes of doing who-knows-what with grain, magnesium, and some kind of car filter. i don’t have the slightest inkling of what’s actually in this knife but I’m happy to be here

相変わらず何をやってるのかはよく分からないけどなんか面白い不思議 最先端？の道具もあるのにちょいちょい原始的な方法で作業してるの好きなんだよな

That ending made me burst out laughing xD The shaking thumbs up hand. Your hand is always so expressive, we need to give it an Oscar xD Thank you for the great content as always

You still have my vote with your sword-smith skills! Its been quite awhile since i watched any of your videos! I enjoy the quiet asmr process!

0:00 to 0:50 witchcraft 0:51 to 18:21 Alchemy 18:22 knife 19:21 cucumber 19:25 testing sharpness of candle knife in the dark but feels like witchcraft 19:43 final product but giving off classic american horror film vibes for some reason

発想力が異次元 クオリティが異次元 手の綺麗さが異次元 流石です

不審者そろそろ来る頃かな？

この人は今頃空気から包丁でも作ってるのかな？

高校化学修めてやっとこの人が何やってるかわかるようになった 習ったことが出てくるとあっこれ授業で見た奴〜！ってなって楽しい

普通にお店で買ってきた蝋燭を溶かして作るのかと思ったら、まさかの蝋燭も１から作るとは… そしてそれで包丁まで作り上げる！やっぱこの人凄いな！！

このチャンネル、いつの間にか包丁出来てるからすき

更新されてないけどお元気でしょうか....

6ヶ月の集大成がたった20分で観られていいのか…○時間ドキュメンタリーでも全然観てられますわ…。 相変わらずエグい発想力とエグい機材に感服です…不審者家機材ツアーとかあったら絶対見たい…。 その内今までの胡瓜登場シーンまとめとか作られたらとても嬉しいです…(個人的推しは水と油婚活の不審者さんがｱｯﾂｱｯﾂ!ってなってるやつ)

This dude is a genius alchemist. Brings humor in the mix. Too bad we wont see another video for another year.

昔の動画は多少なりとも何やってるのかわかったけど最近のはほんとにわからないw

From start to finish this felt like watching a NileRed video in the sense he has access to a fully stocked lab and workplace for the required materials, but decides to do it at home because he's trying to pass on his wizarding ways for the common would-be spell caster. 10/10 I could watch you spend 10 hours making playdough into a machine gun and be happy with whatever the outcome is.

6ヶ月の集大成を20分にまとめてくれて感謝です！

Thank you kiwami japan. You deserve all of your success. Your work is phenomenal and your spirit is infectious.

相変わらず癖がすごいんじゃあ 何喰ってたらこんな思考になるのか（褒めている）

物作りレベルが高すぎて何してるか分からない とりあえず凄いしか言えない

お久しぶりで相変わらずの不審者感、安心感の極みでございます このとてつもない労力と時間と金をかけ、全て溶かしていくスタイル最高です 毎度至高の時間をありがとうございます 次回作を楽しみにしながら鬼リピすることにいたします

この人のヤバい所はマジで何してんのか分かんないのに気付いたら包丁になってる所なんだよなぁ〜

ちゃんと生きてるかなぁ…

this man was gone for the full 8 months making the knife, a dedication to the craft even when the viewers are losing hope...

途中経過が何一つわからないけど面白い 不気味すぎて不審者かよって思ったけどそういえば不審者だったって毎回納得する

しばらく動画上がらないなぁと思ってたら蝋燭作ってたのwwwwwwwwww

分液漏斗自作する人初めて見た 天才すぎだろ

毎回このクオリティ保つの流石としか言いようがない そして狂気は増していく…

I must admit I got chills down my spine when i saw the hydrogen part. Although it's obvious watching your videos you know what you're doing, seeing a jar of hydrogen in this environment is terrifying. This channel never stops to amaze me, thx dude

趣味がコメ欄の日本語探しになりそう

中高生のころ見てた時はなんかすげえって感じだったけど大学生になった今久しぶりに見てみたら大学実験やってるみたいでめちゃくちゃ面白いなって思った。 やっぱ人間って年月たつとものの見方が変わってくるんだなぁとしみじみ思ったいい動画でした

As an ex chemistry student, watching how he improvises some equipment by using common things just makes me feel so much pleasure and satisfaction

I love how he clearly meant to make a pentagram summoning circle at the beginning but accidentally made the Star of David instead

Love this! Easily the most cursed thing you've made so far (and I've been watching you from almost the very beginning, so I should know what I'm talking about) keep up the amazing work!

最後狂気っぽい演出してくれてるけど それまでの過程で充分狂気やでw

i feel like his videos are slowly wearing us down to the point where he can make a "sharpest human flesh knife in the world☺️" vid and no one would bat an eye

He made stearine which is a kind of wax, that doesn't get gradually softer when heated like the common candle wax paraffin, but melts more like water. Paraffin is made from petroleum products, stearine is always plant or animal based.

途中から何をしているか全然わからなくなった、この人本当に包丁作ってるのか？と不安になるがやはりこの人は包丁作ってる人だ、と安心しました。

最初から最後までよくわからないまま観た 毎回いい動画で執念を感じる

Ladies and gentlemen, you who have come in search of answers, rejoice and despair, for I have arrived. Sadly, while i understand most of what kiwami is doing, I find myself clueless about what he did near the end, i have hypotheses, but that do not provide good answers. First of all, because even satan doesn't want to have anything to do with this man anymore, Kiwami resorted to make sacrifices to Yahweh. Or at least that was the intent, but only death answered. Are we really surprised ? Anyway, after tormenting some rice grains that clearly didn't expiate their sins, kiwami is left with Rice Bran. To my relative surprise, this thing apparently contains some oils, and this is something that actually exists and is harvested industrially, not just some whacky essential oils for people with too much money. In the industry oils are extracted by pressing with enormous force, but an other way to proceed is to extract it chemically. To that end, he suspend the bran in some organic solvent, i.e. some liquid in which the oils will feel at least as confortable as in the bran itself, or more. so the oils will leave the bran and dissolve in the liquid. Hence "solvent" Once that's done, he separates the solid part of the solution with a filter, and tries to remove the solvent by boiling it off. At this point he realises that a bunch of weird crap were also extracted with the oils and he doesn't want it. This gooey thing is probably a mish-mash of sugars and proteins, which probably means he used ethanol for extration. Hexane would likely have been cleaner, but that's also a lot more toxic. He scoops the thing up and eats it. Prove me wrong. He then pours the oily part that's left into some water and stirs. There is no explanation of what he's doing because he knows i'll be wrinting this and wants to make it harder to me, but i won't be mislead. he's most likely just "washing" his oil. it's actually the same as what he did with the bran : he's maximizing the contact surface between the oil and the water to allow as much water-soluble molecules to wash away in the aqueous phase. The then uses a quite unorthodox setup with a funnel and a large pierced straw that acts as an high precision tap to separate both phases. That works for the most part. the oily part shows strange bubbles, but that's likely just some emulsified oils (a suspention of micro-drops of oil in water, or the opposite) or maybe there is still some other molecules mixed together. He now takes a strong alkaline solution (=basic, the opposite of acid) and adds it to some of his oil. This is a classic saponification reaction, in living things oils are usually in trigliceride form, which is a molecule of glycerol (a small molecule that likes water and can bind three other molecules) bound to three fatty acid molecules. saponificaiton is essentially separating those elements, which results in free fatty acids that like to combine with dirt and grease and makes it easy to solubilize and wash off. In one word, soap. Of course before it comes to that, he has to separate the watery soapy solution from the oily layer. I suspect he didn't put a lot of alkaline solution, otherwise all the oils would have been saponified. If you’re interested in how to make soap, go watch NileRed videos on soap. The oily supernatant looks kind of nasty, but by centrifuging it he can break the emulsion and obtain a nice clear oil. On the other hand, what was the bottom layer is now essentially diluted soap. he dries it off to show us that it is indeed, soap, but right now he wants to flex his hydrogen-making skills. This part is of dubious utility, to the point where i think Kiwami may have forgot to show us some steps near the end, or he did all that stuff thinking that would all come together at the end but it did not. Or it's an elaborate plot to confuse me. I don't know, i'm not in his head. I would like to say "thank god" but i'm not a 100% certain to be much more sane, so... Anyway, let's get back on track, what he's preparing here is the necessary to saturate the fatty acid carbon chain. Long story short, fatty acids have a long chain of - (CH2) - but some have double links - CH=CH- so there is sort of 2 hydrogens "missing". More importantly, this causes a "bend" in the structure of the fatty acid and prevents it from stacking nice and tidy. Generally speaking fatty acids like to "stack" in order to isolate their carbon tail from the water, and the tidier the arragement the more energy you need to scatter it. In other words, fatty acids with less double links have a higher melting temperature. Now the hydrogenation he’s trying to do requires a catalyst : some element or material that will facilitate the reaction, but is not consumed in the process. Here he took a catalytic filter from a car muffler, but he only needs the Palladium (Pd) part. Of course he needs so supply the hydrogen that is going to be added to the fatty acids, and for that he puts citric acid in his magnesium soup. As we saw in the previous video, magnesium wants to to give up to two electrons to whatever wants them, so it gives them to water in Mg + 2 H20 → Mg2+ + 2OH- + H2. What part does the citric acid plays in this story ? Well it just serves to keep the pH low. The citrate will give a bunch of H+ to the solution, which will cancel out with the OH- to form back regular H2O. This is necessary because otherwise the solution becomes saturated in OH- and stops, meaning hydrogen would no longer be produced. Welcome to the fun world of chemical equilibriums, one of the few fields where you may actually need to solve a quadratic equation. I was shocked the first time it happened, but that’s okay, I ran for my life and became a biologist. I’ll skip over that stuff, basically expose the right ingredients (unsaturated oils + hydrogen + catalyst) to each other and cook for a while. Again go watch the Nilered video on making margarine if you want to know more. But yes indeed, that gross thing is technically margarine. Now what confuses me is that we’ll NEVER see it again. What was the point ? Are you hiding something from us Kiwami ? You're playing with my mind aren't you ? Back to the soap again, now this thing is most likely a bunch of dried free fatty acids, and what he’s doing now is mildly confusing. Again I can only assume this is some sort of wash because nothing is really changed here, he melts them and somehow the high salt amount forces it to remain as a very thin solid ? He then scoops it up and wash the excess salt before drying it again. Aren’t we back on square one ? Now he re-melts it but this time in acid, it looks more like wax and less like oil, which would make sense if he had mixed in some of his margarine with the soap to make it estherify, but after watching this part a good 16 times I see absolutely no indication he did any of that and it is driving me crazy. His wax is kind of moist because… well he just scooped it from a water-based solution. so he melts and dries it on a hot plate with some devices to prevent moisture from coming back, but again, he pushed it so far that I wonder if he’s not actually trying to oxydize his oil ? I mean if it is oil and not a margarine-soap esther, but I don’t know what is what anymore ! This has clearly become wax, it seems harder than paraffin but I cannot tell why because I don’t know exacly what paraffin candles are made of, and I cannot be sure of what in hell he just made. How dare you do this to me kiwami ? You've won ! I don't understand anymore ! My grip on reality is weakening, I can feel it ! And during this time, he is calmly making a knife out of this ungodly creation born of unexplainable chemistry

半年ぶりの投稿めっちゃ嬉しい笑 どこでこんなに知識を得てるのか気になって夜しか寝れない。

this channel has come a long way the chemistry is really getting advanced now

the production value on the props is insane

やめちゃったのかなって思ってたらまさかの蝋燭づくり。することすべてが職人技

I must have asked "Is that the wax?" at least 10 times throughout this video

不審者通り越して狂人になってて草

今こうして過去動画を見返してる間も不審者は包丁作ってるんだろうな

7:16 ここ最高に狂気。 今年も不審者が元気そうで何よりです。

finally, when the world needed him the most, the greatest bladesmith in all of japan has returned

I keep thinking there cant be a reason hes doing some of this and then it just all fits together and somehow makes sense in the end, this is genius

またそろそろかなあ

最初は包丁研いでるだけの人だったのに... こんなに包丁作りに時を費やすとは圧倒的不審者の極みだよ！！（投稿すごく待ってました）

I knew this video was going to be wild from the intro, but when this man started milling grain for fun I started screaming.

I love that he used easily attainable ingredients so I can follow along at home🥰

全然上がってないからTwitter覗いたけど、3つ前くらいの投稿に　一年あがらなかったら死んだと思ってください　ってあった。まだ半年だけど心配🥺

久しぶりの包丁作り楽しみです！

1個の包丁作るのに時間かかりすぎて日に日に投稿頻度遅くなってるの草

I have no idea what I'm watching half the time, but I'm still enjoying every second of it

missing your videos, love watching you make these

This video took 6 months not because of the extremely low yield of his method, but because of the amount catalytic converters he had to *acquire.* Joking aside, the dedication to this extremely niche craft is astounding. Best wishes on your future endeavors in knife making.

半年間制作してたのは流石に驚きしかない いつも自分の想像の上を行く発想面白すぎる w ほんとに名前に恥じない圧倒的不審者の極みww

久々に見たけどいろいろなものでよく作れるよなすげーわ。

The stories in the videos are always enjoyable. You're hard work and efforts are seen and appreciated by all! 😇🤲

シンプルにお人形に本当に呪われないか心配になった…🤭 でも久々の包丁作りがみれて嬉しいです🌝

It took 6 months to make this knife, the dedication this man have is amazing !

Havent watched this guys videos in a while and i'm a little more concerned for him than i was before

I hope we get another video soon!! I can’t imagine how awesome it’s gonna be but I really enjoy the content. It’s been such a long while I hope everything is well with you!

この人の動画への印象が尊敬から恐怖へと変わった今日この頃

"Oh neat he's gonna make a knife out of wax." *Confused as to why he doesn't just melt the wax into a mold* *Thinks about it.* *Totally remembers this channel again* "Holy shit he's gonna make the wax from scratch!" *Instantly impressed*

Honestly, i really love kiwami's kitchen, its so clean and the tools are adorable

Whenever I watch this guy's videos I keep thinking "where is he going with this?" and then suddenly out of nowhere he has a knife 😂

In the past, i remember thinking "this guy is going to run out of materials to craft a knife at some point, right?" I was wrong, you're a genius and my mind cant even comprehend how you work. Good job!

ロウソクを米ぬかから作るのも凄いし、それ以前にロウソクを包丁にする発想が 想像を超えてくる

Hey Kid…just accidentally found one of your videos the other day and my spouse and I haven’t stopped watching them! We especially love (and sorta GET) your sense of humor! The first time I saw you use a “Barbie” doll to shake something; we were hooked! Also, your use of many “gadgets “, especially the whetstone set; have me trying to find them (at a good price)… You are pretty Fn amazingly creative, ingenious, and once again, that sense of humor; AND what’s with the zucchini!? Or is it a cucumber.? Idk. But you’ve got two new fans and we appreciate your “cleverness “. I hope you keep thinking of unconventional shit to make more knives! (I’m a pretty serious knife collector, so you can understand our infatuation! Maybe!?). Just wanted to tell you how much we’re enjoying your Tubes! Keep up the great/ODD work! How about a blue-jean knife? Carrot? Flooring? Stuffed bunny?

New season of Dr. Stone is amazing.
