The best thing since sliced bread, has got to be butter. So what's the best thing since butter on sliced bread? A knife that melts the butter as it cuts into it. Genius!
The knife, is designed by a company named Warburtons, heats up to 41.8 degrees Celsius. It's powered by AA batteries in the handle, and melts the butter just enough to spread smoothly, without ruining the bread.
A button on the handle activates the battery-operated heating element and a flashing LED indicates it is on. The prototype can spread butter over a slice of bread in 30 seconds!
Unfortunately there is no clear indication as to when this will be released, or how much it'll cost - but this is a winning idea fo' sho!
