Making a bismuth knife to undo an injustice

I attempt to undo an injustice and re-create the bismuth knife that should have never been destroyed.

    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.

    i will easily admit that it looks like an awesome knife but I almost wonder how it would look if you made a mold of the kitchen knife and cast formed the blade and used a belt sander to sharpen it.

  • SilkHatchet

    8:15 Not a jab, just tips here! If you ever wanna use a jeweler's saw in the future, make sure you have the saw blade in so it's taught/tight so it'll cut a lot better and faster, and don't shift the angle while cutting so the blade doesn't break ( often...). Jewelers go through tons of sawblades so no shame in that lol

    I'm a dumbass for thinking you were going to extract the bismuth from pepto bismol and then make a knife out of it. That'd be a fucking nightmare in all aspects.

    I’m a jeweler and a horologist in training. From what I’ve seen from your projects, your technique is almost there, and like all craftsmen you just need more practice. I never worked with bismuth, or most of the metals, but if you ever need some advice I’d be happy to give it to you! Just reply to my comment and we’ll figure out a way to talk. I love your channels btw! It sparked my lost interest in chemistry and I have a lot of fun watching your videos. Good luck with the next projects and experiments and thank you for your work!🤗🤗

    i think i've deduced the main issue, aside from the complete lack of preparation on the task at hand, your knife is WAY too thick, like doubled in size, i dont exactly know what kiwami did but they get a light layer of crystals ontop, whilst your knife gains a thick layer of metal and then crystals, might be worth a retry with some research and prep
