Aluminum is one of the most commonly used metals. In fact, it is one of the most abundant elements on earth. So why is it that people never mention aluminum when making knife blades?

Well, despite being lightweight and durable, aluminum is extremely soft. That means a knife made from aluminum would dull quicker than you could sharpen it. But that hasn’t stopped some enterprising knifemakers from experimenting with aluminum blades.

In March, one of the most creative knifemakers in Japan made a fantastic kitchen knife out of a roll of aluminum foil.

Aside from that Japanese knifemaker, few are more skilled or creative at the videos turning everyday objects into knives than Steve Miller from Miller Knives. I’ve highlighted his videos in the past — such as the time he turned a rusty wrench into a knife or the time he made a folder out of a bullet — but he too took on the challenge of making a knife from aluminum foil.

Here is his video from April.

To be clear, these aren’t made to be very good knives since they will not hold an edge or stand up to better stainless steel knives. However, they do show the kinds of things you can do if you just put your mind to it.
