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.
