Lightsaber: A Sci-Fi Take on the Common Kitchen Knife

??It might only be a concept, but this knife design from National Taipei University Of Technology student Chia-yu Yeh is something for our inner sci-fi and culinary nerds to get excited about. The Lightsaber Knife was an entry in this year’s Electrolux Design Lab competition and brings in a few sci-fi aspects past its namesake, starting with a “liquidmetal” blade that can be interchanged with the press of a button.

All adorable child light saber videos aside, the thought is that the user will be able to switch the blade type using the fingerprint scanning touchscreen. This kind of futuristic design thinking throws me back to the toasting knife that makes a memorable cameo in Hitchhiker’s Guide to the Galaxy.
