A replaceable wear part device for attachment on a forward edge of a work tool includes at least a portion of the forward edge of the work tool that has an attachment section having spaced engagement surfaces. The wear part device has a complimentary attachment section provided with spaced engagement surfaces in which the respective engagement surfaces may mutually and slidably engage to hold the wear part device attached to the work tool. The wear part device has an elongated eminence arranged crosswise to the intended operating direction of the work tool, and immediately forward of the attachment section of the wear part. The eminence extends laterally across a first sliding surface by a distance at least equal to a distance between the mutually engaged engagement surfaces.
