Abstract: The baking pan which may have various forms has a substantially metal base and a substantially metal side wall connected by a flexible loop. The base comprises first and second metal segments that are connected by a flexible strap-like band. One edge of the band is connected to an edge of the first metal segment and a second edge of the band is connected to an edge of the second metal segment. Both ends of the strap-like band are connected to the first edge of the loop. The band can flex along its length to allow the metal segments to move with respect to each other to aid in the detachment of baked food from the base.

Abstract: A knife grinder comprises a housing, wherein a grinding mechanism is arranged. A magnetic body is arranged under the grinding mechanism to attract metal scraps. Since the magnetic body is arranged under the opening, the knife grinder allows the metal scraps to be fully attracted to the bottom of the housing, thereby maintaining a clean environment during the grinding process.
