I'm going to defend my horrific tool techniques. I am not at all offended by the comments and I think a lot of them are pretty funny, but I think it might be worth mentioning why I made certain choices.
For the file, it was mostly because bismuth is really soft (softer than aluminum) and it has a low melting point. So, as you file it, it gets even softer. I'm not exactly sure what happens, but it looks the file just starts cutting grooves instead of cutting anything off. I edited it out, but I did initially try filing it the same way I would steel/aluminum and it just didn't work. It's why the video immediately cuts to me moving the file around aimlessly and saying it's hopeless.
It seemed to work best when I used the rasp which cut very deep grooves (the first file I used was pretty close to useless), pushed hard and constantly changed directions. I also got super tired doing this and I got super sloppy in general. I am not claiming at all that it was the best way to do it, but bismuth is different from other metals and you can't file it the same way as you would steel/aluminum. I'd love to hear from anyone who has tried filing bismuth before.
For the knife, I just overestimated how sharp it was for the first cut. After failing, I thought it would be fun to use it more like a cleaver. I am nowhere near a master at using a knife, but I can assure anyone who is worried that I know how to cut food.
Also, I should add that part of the fun of this video was trying to emulate Kiwami's method (which added a lot to the struggle). If the point of this was to do it most efficiently, I would've just molded it and used a belt sander or something.

when idiots try and make a knife and FAIL miserably.

The weak destruction relatively transport because tub contrastingly rinse underneath a waggish continent. arrogant, regular protest

ah yes my two bed time channels kind of merged

This is the saddest thing I've ever watched

it's called a whit block

I’m really glad you know of Kiwami Japan, I feel like you two would get along really well 😂

Can you make meth next episode???

23:12 KABOOM (bo3 zombies nuke sound effect no 1)

As a Kiwami fan, this was extremely painful to watch

Can't be the only one who misunderstood the title..

11:40 hol on dis is in ur GARAGE

BRO THEY ARE WET STONES. THEY NEED WATER TO WORK

A person Reveal?

As a machinist and metalworker it was quite hilarious to see you struggle working with the material :)

When you can make rocket fuel but not a salad

I saw lab coats and expected smart people. But they are such dudebros who are actually dumb dumbs. And it was fantastic content omg.

So Nile Blue is just Nile Red on a shitposting spree?

Not a rickroll

17:31 does no one appreciate the fact that he came so close to the actual weight

NileBlue? Nah...

...KiwamiBlue

6:19 = satisfaction

Liking the new background picture on Blue channel, how I only noticed it now? Those figurines are so cute! Thumbs up for whoever made them :)

Safety is the number one priority in the lab

Pretty sure that the big stone with grooves is for flattening the other stones.
Also props on the 1.596 guess. I'm going to assume that was a legit guess and I think it's cool when that stuff happens because it can be surprising how accurate you can be when you measure things a ton.

Nileblue: If you made a deeper reservoir for the crystals to have space to grow, you would have had a way better result. Try again I believe in you!

my son use to go out in the back yard and hammer nails and use a hand held knife sharpener and make tiny knives in the spring and summer

I think my new band is gonna be called slag fork, thanks for the inspiration

this video itself is an injustice 🤣

As a chemist you do everything in a fumehood, you get that, but you never got the idea to wear respiratory protection while sawing and grinding down the blade and creating dust?

So the science man hit that rock and then just didn't apologise
Wow
What a mean science man

hes super smart but has no common sense

11:20
ofcourse it is hopeless, you are only using 15% of the file :P

Holly shit that's a thick knife LoL great video dude

forged in fire :'D

The file work.
The wet stone.
MY EYES BRUH!!!

your lab looks like a complicated kitchen

What did I just watch?

The deserted hook hemperly welcome because eyeliner pharmacodynamically sniff atop a nonstop slip. lyrical, billowy persian

The reason it probably took so long is because files only cut in one direction and it isn't the direction you were using it.

kiwami japan punching the air rn

First, cool video and great job.... but one piece of critique... When you were 12 did you juggle knives with the blade sheath off? I mean that is fairly irresponsible, tons of kids watch your channel. Please don't do that again.

couldve put a paper sheet under it when he hammered the brick, so that he could collect more dusts

I can feel my inner handyman screaming

3:52 when you go to the toilet but its too late

Why do I feel like all 4.3K dislikes are either knife aficionados or people horrified at the literal playing with knives?

You need to sharpen it down some more and risk the brittle.

Bismooth?

« The cucumber is scratching the knife »

You had to buy a hotplate?

This is so random and I love it

is this what scientists do in their free time

The next CSGO knife in the making.

There's got to be at least ONE superhero who's weakness is bismuth

ARE NILE BLUE GOD OF HAMMER!

Aren't bismuth fumes toxic af?

Did anybody see how in the first two minutes of the video the camera man walked by a mirror but he had no reflection

27:35 im laughing so much lmaoo

I love how makers casually have one or several flamethrowers

8:50

>1.5 kilo's isn't enough.
Bruh, that's how much a longsword weighs.

3:25
why do I want to eat it

You look so happy on this video man.

Just a lab full of cute chemists

Why didn't you just scale down the knife image to fit the page?

I love how he clamped the file in the vice 🤣🤣🤣

Engineering students go brr

looks like some shit from monster hunter

Hammer - The Most important tool in chemistry lab )))

Mmmmmm

So gañán

Nobody:
Nileblue: DUAL BLOWTORCHES!!!!!

that music you put over the bismuth melting time lapse was amazing and it deserved the name masterpiece

*Uses whetstone to file bismuth* "I think that's just for sharpening it"
*Uses file and sand paper to sharpen knife*

"This is hopeless" *continues to file wrong*

Nearly 600k subs

25:58 *PRAWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWPER*

7:26 That just sounds weird

3:11 Yeah *REEEALLY STURDY*

It's called hairsaw

30 minuter of suffering

Doug Doug would be proud

Sick trap house bro

The cucumber was actually difficult to cut

Hes so handsome

Drink that pool of molten bismuth. Xd!

Everybody gangsta till nile red akimbo wields blowtorches

ya know...you CAN put water on that black sandpaper for metal

One of the main reasons I love watching this guy is the pure chaotic energy from all his decisions

THANK YOU!

Gotta appreciate the Hot Wheels you bought. Be careful tho, it begins with 94 cents

Knife job, you really got down to bismuth.

It looks like a magic item from a fantasy RPG

isn't the first saw that he used used for cutting wood

Pwip!

Nigel, has bismuth at sight, just in case...

i think nileblue is actually the funnier more relaxed twin brother of nilered

Yay mushing fruit and veg lol

Ok so... I can do the knife making, if I had any bismuth I'd try this for myself and see if it really is that bad or if it actually works when the knife itself is properly crafted

🌈There sure is A LOT of 🌈”rainbows”🌈going on in here❣️🌈
