The (arguably) less-acclaimed movie adaptation of The Hitchhiker’s Guide to the Galaxy did contain a scene where they showed an ingenious method of toasting breads – by slicing the loaf up with a red-hot laser knife. Well, mad-as-a-hatter British garage inventor Colin Furze (along with some of his fans) was seriously inspired by this futuristic yet potentially dangerous kitchen gadget. As a result, he came up a similar gizmo named ‘FurzoToasto’ that entails an actually heated saw blade (yes, you read that right!). So, when passed through a loaf, the sharp (and hot) instrument cuts through the bread to effectively toast its side sections.

Now the question arises – how does Furze get this saw to be heated up in the first place? Well, the answer lies in a setup involving a modified microwave transformer, a few copper wires and of course some hard wiring. In other words, electric current runs through the saw, thus increasing its temperature to an intensely hot magnitude (a red-hot condition which is actually visible in the dark). In breakfast terms, this translates to immediate transition of normal bread into a toasted slice – without the ‘timely’ intrusion of those dastardly toasters. But be warned – heated saws generally tend to have some…uhm safety issues.
