There goes the saying “So-and-so is the next best thing since sliced bread”, but there are moments when you just want some butter on your toasted bread. Unfortunately, many a time the entire block of butter is just too cold, which means you cannot end up with a nice spread of melted butter, which is why necessity being the mother of all invention has resulted in this heated butter knife. AA batteries located inside its handle will be able to heat up the knife to 41.8 degrees Celsius, which is said to be the ideal temperature so that there is a perfectly thin spread of butter across your toast.
