An ultra-hard and metallic construction comprises an ultra-hard component that is attached to a metallic component via a braze joint. The braze joint is interposed between the ultra-hard component and the metallic component, and comprises a first braze material bonded to a surface of the ultra-hard component. The braze joint includes an intervening layer in direct contact with the first braze material, and that is formed from a rigid material. The braze joint further comprises a second braze material that is interposed between the intervening layer and the metallic component, and that is different from the first braze material. Configured in this manner, the use of the braze joint operates to provide an optimum level of bond strength within the construction to enable its use in certain demanding wear and/or cutting applications.
