I bet your butter knife is not as cool as the SpreadTHAT!. You see, this is a butter knife that is heated. It takes the pain out of spreading butter on your toast. It has a copper alloy tube and draws heat from your palm and transfers it onto the butter. That means you don’t have to deal with any batteries or power sources.
SpreadTHAT! is sturdy and works on peanut butter, chocolate, and other ingredients. It is safe to use and costs as low as $15, but you have to be an early Kickstarter supporter to get it at that price.
