With a roll of aluminum foil, some heat, a small hammer, a few whetstones, and lots of repetitive tapping and sanding, layers of foil can be turned into a sharpened kitchen knife. In the video above, YouTuber Kiwami Japan diligently forges the layers of aluminum, sands and sharpens the metal, and then adds a wooden handle. It’s all created carefully with hand tools.

Kiwami Japan is known for making kitchen knives from unusual materials like chocolate, pasta, and the heaviest, hardest wood in the world. This experiment in aluminum, the video’s notes indicate in Japanese, were handled with extra safety and care. As always when making, mind smart safety procedures and appropriate parental supervision.
