Abstract: A fishing lure having a head member with a straight bore and a core wire extending through the bore from a leading end to a trailing end of the core wire. A fishing line connection is located at the leading end in a position spaced from the axis of the bore to maintain the lure in a generally horizontal position. The head member has a leading face at an angle to the axis of the bore for pulling the lure downward and from side-to-side as it is pulled through the water. Body means such as a spinner blade and at least one swivel bead are mounted on the core wire between the head member and the trailing end of the core wire where a hook is attached.
