VIDEO: How to sharpen a knife on the window of your car

This intriguing video from the USA shows how to sharpen a knife on the window of your car or ute. I’ve no idea if it works or not but, if it does, it would be perfect for those times when you forget your sharpener – which for me is often. If you do try it, I’d love to hear how you go.
