A sharpening device for cost-effectively sharpening dulled saw blades and a method of making and using the same is provided. The sharpening device may form a tooth-like configuration adapted to rotatably grind and sharpen a saw-teeth configuration into a saw blade. The tooth-like configuration may be provided by a plurality of grinding discs and spaces alternatively stacked in a stacked configuration along an arbor that can engage a hand-held power tool. The stack configuration may be retained on the arbor through various stop mechanisms, such as a built-up section or a collar with a set screw. To prevent the stacked configuration from spinning on the arbor from torque transmission, a key way design utilizing a groove cut along the arbor and a complementary arbor hole notch may be employed. Alternatively, the arbor hole may have a shape that matches and mates with the shape of the arbor.
