One of my favorite genres of YouTube videos is watching people make knives out of unusual things. No one is better at this genre than a YouTuber known as kiwami japan.

I mentioned his work in a blog post about two months ago relating to knives made from rolls of aluminum foil, but one of his more recent videos takes the cake.

The Japanese knifemaker makes a functional and razor-sharp knife out of gelatin. That’s right, that soft liquidy substance made from extract from boiled skin, bones, and connective tissues of animals was turned into a knife.

Take a look at the magic happen.

This isn’t the first time the YouTuber has made a knife out of an odd substance. He have used pasta, chocolate, foil, ice, wood, and even a piece of fish. Surprisingly, the gelatin knife was the third sharpest knife just behind carbon fiber and pasta.

What I really enjoy about these videos is not just the ingenuity but the process and tiny details. You see all of his idiosyncrasies and go through a circular journey. With the gelatin, he not only opens the packages of gelatin and turns them into a knife but then turns the knife back into gelatin and reseals it in the original packages for consumption.

For those interested, here’s a look at the carbon fiber knife video:

Interestingly enough, YouTuber Cedric & Ada Gear and Outdoors just did a video review on a full carbon fiber pocket knife. Needless to say, he was not at all impressed with the knife.

If you’re not yet subscribed to as kiwami Japan on YouTube, what are you waiting for? These are some of the most entertaining, hypnotic, and creative knife videos coming out right now. Now excuse me while I go make some Jell-O. I can’t wait to use my Leek made of leeks to cut it.
