What tool is used to cut fat into flour?

Here are other tools that can be used:

* Two knives: You can use two knives to cut the fat into the flour, but it can be a bit messy.

* Fork: You can use a fork to cut the fat into the flour, but it will take longer and may not be as even.

* Food processor: You can use a food processor to cut the fat into the flour, but it is important to not over-process the dough.

The goal of cutting the fat into the flour is to create small pieces of fat that are evenly distributed throughout the flour. This will help to create a flaky and tender pastry.
