This Freaky Knife is Carved From a Giant Piece of Actual Petrified Fish

Meet the baddest piece of sushi ever.

There’s something very fishy about this knife. 

It doesn’t have blade forged from military grade stainless steel or a handle made of carbon fiber composite. 

Rather, the entire thing is carved from a block of dried and smoked bonito tuna called Katsuobushi—a Japanese preparation that holds the Guinness World Record for the hardest food on earth.

When shaved into flakes, Katsuobushi imparts umami flavor into the dashi fish broth used to make miso soup. 

As this YouTuber demonstrates, one can also craft a hunk of the stuff into a full-size blade. 

It may not be as flashy as these pocket knives made from Woolly Mammoth tusks and dinosaur bones, but it’s still pretty badass.
