What is the tool used to cut butter into flour?

It looks like a wire whisk but with two rows of wires that are curved and pointed. The blades are used to cut the cold butter into tiny pieces within the flour, ensuring a flaky texture in the final product.

Here are some other common tools used for this purpose:

* Fork: You can use a fork to cut the butter into the flour, but it may be a bit more time-consuming and less even.

* Two knives: You can use two knives to cut the butter, but be careful not to overwork the dough.

* Food processor: You can pulse the butter and flour together in a food processor, but this may result in a slightly less flaky texture.

No matter what tool you use, the key is to keep the butter cold and to cut it into the flour quickly and efficiently. This will help to create a light and flaky texture in your pastries.
