London: A new hi-tech butter knife has been invented that would allow people to spread the cold-solid butter taken straight out from the fridge.
The 'SpreadTHAT!' blade uses a revolutionary heat-transfer system which harnesses body heat to melt through the butter, allowing it to easily spread onto the toast, the Daily Express reported.
Designers claim to have developed a copper alloy tube which instantly transfers heat from the palm to the end of the blade. And weighing just 2.91 oz., the blade uses no electric or batteries, no heating or hot water, and most importantly, needs no heat-up period.
The Kickstarter campaign, which was launched at the start of August, has now raised 33,500 dollars with 18 left to go. The team behind the device, based in Seattle, hope to have the product in mass production in December.
When it finally hits the shelves, it is expected to retail at a price of around 15 pounds.
