Piko Piko Hammer

The Piko Piko Hammer, also called the Love Hammer, is an object in the Sonic the Hedgehog series. It is a large yellow and red hammer and Amy Rose's signature weapon, which she uses as a melee weapon and to perform special techniques.

The Piko Piko Hammer commonly resembles a double-faced sledgehammer or mallet. In most cases, it has a red head with yellow faces. In some portrayals though, these colors have been inversed.

The first Piko Piko Hammer Amy wielded had a narrow red head, flexible yellow faces, and a purple handle. Since then however, the Piko Piko Hammer has been portrayed with two consistent designs that have been used interchangeably:
 * The first design depicts the Piko Piko Hammer with a large cylinder-shaped red head with raised rectangular sections around the middle. The face disks are rather thick and have round edges. It also has a brown handle with a metal section where it meets the head. This design first debuted in Sonic Adventure.
 * The second design depicts the Piko Piko Hammer with a cylinder-shaped red head like the first design. However, instead of raised rectangular sections around the head, its head has a smooth surface. Its face disks are also flatter and have flat edges. It also has a brown handle with a metal section where it meets the head. This design first debuted in Sonic Advance.

The size of the Piko Piko Hammer's head often differs. Usually, it is slightly bigger than Amy's head. In other cases]] however, it is much larger, reaching sizes greater than the Pink Cabriolet.
