Abstract: A multi-purpose impact tool includes an elongated guide bar including cylindrical top and bottom ends and an intermediate section having a polygonal cross section; an annular guide disc on a cylindrical top end of the bar, a head for mounting on the bottom end of the bar for delivering an impact force from the tool; a cylindrical sleeve for sliding on the guide disc for impacting the head; a plug in the bottom end of the sleeve with a polygonal hole for receiving the intermediate section of the bar and preventing rotation of the sleeve on the bar; and a lock on the upper end of the sleeve for locking the guide bar in the sleeve when the tool is not in use.
