Resourceful Knife Maker Proves You Can Turn Aluminum Foil Into a Terrifyingly Sharp Blade

We’ve all had to improvise when realizing we’ve run out of clean dishes. A pot becomes a bowl, a ladel a spoon, but finding a substitute for a sharp kitchen knife requires a little more effort. As long as you’ve got a roll of aluminum foil on hand, and some unmatched knife-making skills, however, you’ll be able to avoid washing dishes for yet another day.


Japan’s most resourceful knife-maker is back with a new DIY project that uses actual metal instead of food to fashion a makeshift blade that not only looks like it came from a high-end kitchenwares store, it also cuts like it, too. As with Kiwami Japan’s previous creations, a mastery of knife sharpening is used to create a finely-honed edge that cuts like a razor, and while the aluminum’s definitely not going to stay that sharp for long, the important thing here is finding yet another workaround to loading the dishwasher.




I call Shenanigans! Somewhere around the 2:25 mark he changes out the folded roll for a bar of aluminum.

You can’t just pound aluminum layers together to get a solid mass. The oxide layers simply won’t allow it. If what he did in the video was actually possible it would drastically change manufacturing.

Making an aluminum knife is an ok project. But doing it from a roll of foil as shown here is BS.
