Which metal breaks the rose petals into pieces?

The metal that can break rose petals into pieces is typically a sharp or heavy metal object, such as a knife or a hammer, rather than a specific type of metal. The action of breaking petals is more about the force applied rather than the metal itself. In a metaphorical sense, some might refer to the harshness of certain metals, like iron or steel, as being destructive to delicate things like rose petals.
