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.
