Transform a Japanese Fish into a Knife
We have all heard the saying, “Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.” What the saying doesn’t explain is that the man is fed for a lifetime because he’s able to turn those fish into knives and start a fishy knife business. Dried bonito, or katsuobushi, is considered the hardest food in the world and apparently has many useful applications as food, a hammer, and a knife. To get to this hardened state requires weeks of drying the fish out and fermentation. However, once it does you’ll have a great multi-purpose tool. The YouTube channel kiwami japan even shows you the process of how to turn this dried fish into a knife that cuts. That's right, this knife can cut paper and puncture aluminum cans. The video may only be about 10 minutes, but you can tell that it takes a lot of time and effort to get that blade. What’s your favorite multi-purpose tool?
