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.
