A blade sharpening device (8) easily connectable to a source of rotating power, such as a battery powered hand drill (66), and having a guard member (14), a selectably locatable handle member (16/16') attached to the guard member, and hand-manipulatable means for maintaining the grinding surfaces of the sharpening device at a desired grinding angle and moving it along the length of the blade edge. The guard extends completely over the width of the rotatable sharpening members (10 & 58) and over about eighty (80 DEG ) degrees or approximately a quadrant (ninety degrees) of their sides and provides an upper, curved surface (18) or a side, flat surface (19), depending on which handle location (30/28) is used, against which the user's hand can be rested for greater control and stability of the sharpener when in use on, for example, a lawn mower blade (62) which is still attached to the lawn mower drive shaft (63) at the underside of the lawn mower housing (64). This on-site, in-place blade sharpening capability eliminates the necessity of removing the blade for its sharpening, while still allowing easy and safe sharpening of the blade even in such awkward circumstances.
