The fan blade (20) has a dovetail (24), and an airfoil (18) extends radially outwardly from the dovetail (24). The ribs (26) having a thickness defined as measured from said leading edge (21) toward said trailing edge (22). The ribs have break-edges (38) at ends of the thickness that extend away from an outer face of the rib (26).</p>
