The strike construction comprises a strike tip () and a support body (), in which respective attachment ends () of each of the strike tip and support body are joined to each other, the attachment end of the strike tip is coterminous with cemented carbide material comprised in the strike tip, and the attachment end of the support body is coterminous with cemented carbide material comprised in an end portion of the support body, the end portion being configured such that sides of the support body depend divergently from its attachment end. The method includes providing the strike tip () and a precursor body () for the support body, in which a proximate end () of the precursor body is coterminous with cemented carbide material comprised in an end portion of the precursor body, the end portion of the precursor body being configured such that sides of the precursor body depend divergently from its proximate end, the area of which is less than the area of the attachment end of the support body ().
