A grinding device includes a grinding member disposed on a base, and a board rotatably supported in the base at a shaft. An axle is rotatably secured in the board for supporting the tools. A spring is coupled between the base and the board for moving the axle and thus the tools toward the grinding member and for allowing the tools to be ground by the grinding member. The grinding member is rotated to grind the tools. A rack is coupled to the axle to rotate the tools for allowing the peripheral portion of the tools to be ground by the grinding member.
