A Knife That Melts Your Butter
There are two types of people in this world— those that refrigerate butter, and those that don't. For the ones who like to keep their butter cold, this knife was designed just for you. A battery-operated heater inside the handle makes spreading butter on toast a breeze.
The knife, designed by Warburtons, heats up to 41.8 degrees Celsius, powered by AA batteries in the handle - and melts the butter just enough to spread smoothly, without gouging holes in the bread.
A button on the handle activates the battery-operated heating element and a flashing LED indicates it is on.
