The portable band saw sharpener includes a frame for receiving a saw blade that is to be sharpened. A hand-operated motor is pivotally mounted to the frame for driving a grinding wheel, which engages the teeth of the saw blade. A hand-operated structure releasably holds the saw blade in place during the sharpening of the saw teeth, and the motor is guided along a path matching the contour of the saw blade teeth by a cam and an interchangeable cam track, which may be adjusted for saws of various contour s and dimensions. The portable band saw sharpener is adjustable, hand-operated and portable.
