This mod requires Cut The Fat, and patches the crafting recipes to change two things. 

1) Both the knife AND the cleaver give 4 pieces

2) You can recombine the pieces back into large lumps (by putting 4 back in the crafting grid. Shapeless recipe)

If you've played with Cut The Fat you probably already know why I made this patch. But after having gotten myself into a position where all I had were cut pieces and I wanted to make a fruit press and couldn't, this was the first thing I wanted to do before jumping back into the game.
