The Heated Butter Knife is scientifically proven to spread butter better

Toastie Knife

By this point, we get it, I’m fond of innovative ways to put butter on bread. It’s just so delicious when done right that it’s hard not to be excited when you see a new way of doing things. While you can grate your butter, heat it manually, or just sit it out and wait, there are very fast ways to get things done that will still give you an even spread. Everyone’s passionate about something, right?

 Everyone handles the dairy aspect a little differently, but Warburton’s conducted a poll with a little under three thousand people and found the most common practices were using a microwave, heating a regular knife, putting butter on a plate on top of the toaster, or using a hairdryer to get the butter to the exact desired temperature. The Warburtons Heated Butter Knife is the best option, and is backed by scientific fact. The amount of knowledge they have about toast is astounding. They talk about the “butterability” of the bread, and how the perfect temperature that the butter should be at is 41.8 degrees Celsius coming at the bread at an angle of 24.5 degrees, and how you should use short strokes rather than long when spreading.

While I kind of doubt the information, the copious amounts of it on their site (which is about baking) is almost too thorough to not believe. The handle of this knife will remain cool while the edge of the blade can heat inside of 30 seconds to start spreading that dairy goodness. While this is a hilariously neat idea, it’s only a concept at this point, though it likely wouldn’t cost more than $20 should it hit the market. They certainly seem reputable enough to make this sort of device, but we will have to wait and see.
