- Heated knife powered by two AA batteries in the handle
- Blade with heating element hits 41.8 degrees centigrade - perfect

Hot buttered toast is right up there with a nice cup of tea for comfort and sustenance.
Sadly, making it often ends in frustration when your perfect slice falls apart as you try to spread on a cold lump of butter that just won’t melt.
Now designers believe they’ve conquered the problem by inventing a heated knife.

The knife, invented by British baker Warburtons, heats to 41.8 degrees Celsius after research found that is the optimum temperature to spread butter
The knife's heating element ensures a constant temperature of 41.8 degrees centigrade, and is powered by two AA batteries in the handle
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, 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.
The prototype can spread a slice of bread in 30 seconds - although it's not clear when or if it will be released, or how much it will cost.
Researchers created the knife with bread baker Warburtons after a survey found it is the most desired breakfast innovation.
Butter not spreading properly is one of our top five breakfast bugbears along with burnt toast and cold tea.
Stuart Jones, from Warburtons, said: ‘We’ve fine-tuned the knife’s specifications to ensure the speediest heat-up and perfect temperature for spreading and we’re thrilled with how well it works.

A poll of 3,000 people revealed 1 per cent of Brits - all of them men - have even resorted to heating the spread with a hair dryer to combat the problem.
A quarter - 28 per cent - put the butter in the microwave, 8 per cent put it on a plate on top of the toaster and 7 per cent heat the knife on the hob. The new knife will perfectly cover a slice in butter in less than 30 seconds.
‘It made complete sense to develop a tool to help busy Brits achieve the perfect even-spread on their toast, even when using butter straight from the fridge,' says Jones.
‘Baking is a blend of expert craft and science and to make the perfect piece of toast it is essential to use a good-quality loaf that offers butterability.’ The baker has yet to set a date for production.Â

Could have used one this morning. I usually leave my knife in my coffee to heat up but it`s only good for one slice of toast. I like this idea.

Just stick your knife in your tea for 10 secs and it's hot enough to spread butter!

This is about as useful as a battery powered salt and Pepper mill. (yes they do exist) Why not just run the knife under the hot tap, and then if,god forbid, it gets too hot, you can run it under the cold tap and get it "just right" for that all important transportation of the butter to the toast.

Keep a day or two's butter on a covered butter dish (cost of butter dish extremely cheap, no batteries required) and store on counter or in cupboard. Keep house at comfortable temperature for humans. Butter will be soft enough to spread but not too soft. Ready immediately. When chunk of butter used up, add new chunk to the dish for the next day. Wow, who'd have ever thought that one up other than a few billion grandmothers?

Correction. I use a cheese slicer, the ones made for hard cheese.

I don't believe I would spend the money on this gadget. When I have to butter my toast and the butter is hard. Well there is always my cheese grater. Works great.

i seen something like this on a TV show called 'rules of engagement' a few weeks ago but it was with a spoon for cooling soup

brilliant, i don't know how long 2 AA batteries would last though

Anyone who's used a knife straight out of the dishwasher, knows how impossible it is to get the butter to stay on the heated blade while trying to transfer it to whatever it is you're trying to spread it on. This knife would give you the same problems, I'll pass.

Just leave it covered in a butter dish outside the fridge, It's only the current mentality of people that makes them think, that, to be fresh, all things must be permanently parked in the fridge , but butter will be fine for many many days , you will have finished the block long before it goes rancid.
