This superheated knife toasts bread as you cut it

Tired of having to slice up your fresh bread before you drop it in the toaster? Colin Furze feels your pain. The homebrew inventor just built a toasting knife that -- you guessed it -- toasts whatever you're cutting. It ultimately amounts to a modified microwave transformer sending loads of heat to a blade, but it singes your soon-to-be meal about as well as you'd hope. You can even use it to melt butter as you spread it, like a kind of culinary steamroller. Is this practical for your kitchen? Probably not, but there's no denying that it'd be convenient for those hectic mornings when every second of breakfast-making counts.
