Is it better to include an object in every class or only when it's needed?

Suppose I have the class 'Pizza':

Option 1:

class Pizza:
    def __init__(self, tools):
        self.tools = tools
        self.slices = []

    def cut(self, slices: int):
        self.slices = self.tools.pizza_cutter(slices=slices)

    def eat(self, slices: int):
        if len(self.slices) => slices:
            diff = len(self.slices) - slices
            self.slices[:diff]
        else:
            print('Not enough slices to eat!')

Option 2:

class Pizza:
    def __init__(self):
        self.slices = []

    def cut(self, slices: int, tools):
        self.slices = tools.pizza_cutter(slices=slices)

    def eat(self, slices: int):
        if len(self.slices) => slices:
            diff = len(self.slices) - slices
            self.slices[:diff]
        else:
            print('Not enough slices to eat!')

As you can see it either loads tools in __init__, or it just receives the tools instance in the method that actually uses it.

I am wondering, what is the best approach? Consider that there are multiple instances of Pizza created each loop and that at the end of this loop I cut() all the Pizzas
