Presented is a work rest blade assembly for a centerless grinder that provides multiple wear surfaces on which a work piece may be supported. The work rest blade assembly includes a generally cylindrical work rest bar splined at opposite ends and clamped to a crowned support plate in such a manner that the bar is flexed from end to end to impose a bending moment thereon and is twisted in opposite directions at opposite ends so as to impose a rotary moment on the bar to thus rigidify it.
