The sharpening stone is readily attachable in a chuck of an electrically powered sabre or jig saw. The sharpening stone is secured to a metal device (shaped to fit the saw chuck) by adhesive bonding or molded into the stone. The sharpener is especially effective for sharpening hand tools including power rotary lawn mower blades.
