ABSTRACT OF THE DISCLOSURE A ground-engaging tool is disclosed which includes a blade with a load carrying front face, a ground-engaging bottom surface, and a rear face, and a wear-resistant insert is secured thereto to extend the service life thereof. The wear-resistant insert includes a back-up plate of low carbon steel which is disposed in rearwardly spaced relation from the rear face of the blade and adjacent its bottom surface, a wear-resistant material which is bondably sandwiched between the plate and the rear face, and a plurality of bridging members of low carbon steel which extend through the wear-resistant material and are rigidly secured to the plate and the rear face of the blade to minimize in use spalling of the wear-resistant material. The wear-resistant material includes a plurality of abrassive-resistant particles of low carbon ferrous-based alloy material in a carrying matrix of low carbon ferrous-based alloy material different than said material of the particle.
