Man Transforms Roll Of Aluminum Foil Into Incredibly Sharp Knife

March 27, 2018

Move over, folded steel, because this is a video of knifesmith and Youtuber Kiwami Japan forging an incredibly sharp knife out of a roll of aluminum foil. How about that! I found the whole process incredibly satisfying to watch, especially half awake and mindlessly eating mini donuts. *shrug* It's how I live my life. "But are you really living?" Don't be jealous.

Keep going for the video while I seductively lick a candy cane into an eye gouger. Also, would it have killed him to add a little more cutting demonstration at the end of the video? I spent ten minutes of my life watching him make this thing and he only cuts a cucumber. I might leave a Youtube comment.

Thanks to hairless, who keeps himself clean shaven with a knife he forged from body hair. Sick but cool!

    He could've bought one just as good at the Dollar Store for, like, a buck.

    This was a cringy watch after all the hours I put into Forged in Fire.

    On the Next "Forged in Fire"...

    Also: "Eet weel keel!" ^_^

    Call me when he makes a Mt. Dew can.

    If I use those sharpening stones on my butt, will it get shiny too?

  • But how good is it at stabbing?

  • whacko

    Does anyone else think that halfway through the video he swapped out the roll of foil for a bar of aluminum covered with a single sheet of foil?

    The melting point of aluminum is around 1200°F. Most stoves top out at around 500-600°F. Even with the hammering, he wouldn't really be able to fuse all of those thing layers of aluminum into a solid block that could be sawn without coming apart.

    Especially since at one point in the video he splits the knife blank into two layers. If he could do that, then the sanding to clean up the edge and the grinding on the whetstones would also peel up sheets of aluminum.

    The flame temperature of natural gas and propane is around 3500 F.

  • whacko

    You can get those temperatures out of a torch, but no stove top would get that hot. If you were cooking with 3500 F, it would be nearly impossible to cook any good without almost immediately burning it, even through a cooking vessel. Also, many cooking pots and pans have copper or aluminum bottoms to spread heat evenly and they would be damaged by prolonged exposure to that temperature. The melting point of copper is just below 2000 F and as I've said the melting point of aluminum is just around 1200 F.

  • upsidedownfunnel

    A large aluminum pan acts as a heatsink which is why it'll never get hot enough to melt. An open flame is more than hot enough to melt aluminum if you just have a small amount. A propane torch can be used to melt those aluminum brazing rods which require a temperature of 750 degF.

    I can't speak to the authenticity of this video though. i kinda thought it looked a little fishy when he had a solid aluminum

  • GeneralDisorder

    I'm thinking it would have taken a few tons of force to merge the aluminum... Or perhaps months of hammering by hand. To the google! If I'm not back in four days I probably just forgot what the hell I was looking for.

  • TeknoXI

    Agreed. When aluminum melts, the whole thing melts because of its thermal conductivity. Can't weld the inside when the outside would melt first.

  • TeknoXI

    I have serious doubts to the authenticity of this video. It's like magic he was able to make a solid plate from aluminium foil. Aluminium has an oxide layer and a low relative melting temperature. Heat also oxidizes. Feels very suspicious.

  • Isaiah Rockefeller

    Also...aluminum foil is not 100% aluminum....

  • TeknoXI

    Correct. It's aluminum and aluminum oxide.

  • Adibobea9

    Sometimes one should just enjoy the magic for entertainment purposes without worrying about how the trick was done…

  • The_Wretched

    i like the part where he wets the whet stone with a 3mm opening in a ceramic pour cow.

  • steve holt

    weird.

  • Bling Nye

    Be interesting to know how long the edge lasts on it with any kind of use...

  • GeneralDisorder

    About 6 minutes.
