# Solving the age old problem: Heated butter knives

It’s annoying, isn’t it? The toast is a perfect golden brown, warm to the touch, and the coffee is brewed. You reach for the butter, snatch up a knife — and find it is nothing like the golden and perfectly spreadable butter on television, but an impenetrable block of ice that requires a microwave to soften.

Rather than hoping and praying you don’t go over the single second which turns spreadable butter into a liquid mess, UK company and breadmaker Warburtons have come up with a solution.

The Toastie Knife, no doubt a hat-tip to Warburton’s “Toastie” range of bread, is a prototype knife that the company’s researchers have come up with. Heating to a temperature of 41.8 C (107.24 F) in 30 seconds, the heat is triggered by a button on the handle and an LED light that indicates when the knife has reached the “perfect” temperature. It runs on two AA batteries.

Warburtons went ahead with the knife development after running a poll of 3000 people — and how they warm up that ice-block butter. 28 percent used the microwave, 8 percent used a plate on top of a toaster, 7 percent used a hob — and 1 percent, all men, decided to use a hairdryer to accomplish the feat.

It may not only be our strange methods of warming butter — from microwaves to hobs and hairdryers — but according to the Warburton’s team, our technique may also be a little off.

To get the perfect slice of buttery bread, you need to use the knife at an angle of 24.5 degrees, a vertical pitch of 7 degrees,and don’t forget to start in the middle of the bread, using short strokes to evenly coat your toast.

The knife is currently only a prototype, sadly.

What? Isn't this a criminal waste of energy?

###### My solution
I just leave the butter out all the time (inside a butter dish, covered). Covered butter keeps at room temperature for a long time. You can take it out half a stick at a time, if that works better for your family.
