How can you divide an object into 2/3/4/... parts?

Question

Unity

There was an idea to create a game, but as a beginner there are no ideas and knowledge of how to implement it.
The essence of the game is to click on the screen, the animation for the knife starts and if it passes through this object (fruit), you need to cut it.

As far as I understand, the author wants to divide a large prefab into several small ones, and by and large it doesn’t matter what is there, a mesh or a mesh, the mesh can also be divided, although this will not be very correct. Then from several parts (as I mean) something will be assembled. Google and read about nested prefabs ( https://docs.unity3d.com/Manual/NestedPrefabs.html) in the latest versions of unity this became possible.
