Solved: The problem of spreading cold butter

Today, is a big day for humanity. A big, big day.

Designers have created the world's first knife with a heated blade to solve the age old problem of cold butter not spreading properly on bread. The knife blade heats to 41.8°C (107°F) after research found that is the optimum temperature to spread butter. A button on the handle activates the battery operated heating element and a flashing LED indicates it is on.
