The Sledgehammer is a weapon in Rule of Rose found in the "Rag Princess Sews" chapter. To get it, the player must visit Engine 3 after meeting the first Pig Imp. There, an Imp holding the weapon is found; it will throw the weapon at Jennifer and she can pick it up afterwards. It is the recommended weapon for the chapter, as it can kill a pig Imp in 4 hits. It is the successor to the Shovel.
