In Japan, “prank knives” (also known as “Dokkiri Cutters”) are marketed to adults and children alike as “an absolute hit at parties” – they're dulled down utility knives with a semicircle cut into them made to fool friends into thinking you’ve severed your finger.
But the joke went a little too far once popular Japanese discount store chain Daiso realized they were accidentally selling real, razor-sharp blades. Daiso was forced to issue a recall. You see, Daiso is a household goods store...and sells regular knives. So, it looks like the store accidentally packaged real utility knives and distributed them across the country.
Now, sales of all gag knives are being suspended in Japan.
