ABSTRACT:
A device is provided for attachment to an electrically powered jig saw for the purpose of removing hardened grout from the spaces between adjacent coplanar tiles. The device translates the reciprocal vertical motion of the jig saw to reciprocal motion of a horizontal bar which causes a cutting blade to oscillate in a vertical plane upon a pivot pin transversely penetrating a yoke that supportively embraces the cutting blade.
