A surface mounted sharpening tool having a generally rectangular body which may be formed of one or two sections and which body has blade cavity structure with sharpening blades forming a V-shaped sharpening notch. The body includes a pair of generally parallel guide ridges extending outwardly from the body such that a guide slot is defined between the two ridges or in which the guide slot may be recessed into the body. The guide slot through which the tool to be sharpened is guided is set at a predetermined angle from a right angle to the flat surface of the blade in order to obtain the most favorable sharpening action.
