As far as innovative toasters go, I’ll stick with the VHS toaster over this butter-knife type deal. At least with that one I wont accidentally toast my hand in the morning.
It’s a design concept by Kim Been that looks like a knife but is really a handheld toaster. All you need to do is run it across the bread until it’s toasted to your liking. An animated graphic shows you how you are doing, which your you should be able to see with your own eyes.
How are you going to get toasting power in this knife-thing? It would likely take awhile to toast your bread. Therefore this may be more of a dieting tool as you will surely go hungry.
