Cutting a frozen loaf is not easy and you won't have to thaw the whole loaf with every use.
Wrap up the loaf tightly.
Wrapping the loaf with wax paper or foil will help keep moisture with the loaf and prevent freezer-burn. With soft bread, you can place wax paper between slices to prevent them from sticking together.
