Using a dull knife is like trusting a sleepy sloth to perform delicate brain surgery—it’s not just ineffective, it’s dangerously unpredictable. A sharp blade slices cleanly and goes where you tell it; a dull one, meanwhile, mashes tomatoes into tragic salsa while plotting a surprise detour straight into your knuckles.

Instead of gliding through onions like a culinary samurai, you’re forced to bear-hug the cutting board and press down with the strength of a thousand regrets. That extra force means when the blade finally decides to cut, it leaps forward like a caffeinated squirrel, making your fingers the unwilling volunteer tribute. In short: a dull knife doesn’t just ruin dinner, it auditions your hand for the role of “unexpected garnish.”

All that is to say, this new ultrasonic knife by a Seattle inventor is cool as hell. I really want one. Guess how much it costs? More than you’d like…but probably not as much as it should.
