Abstract
A cutting element is described comprising a super-hard cutting table, a substrate and a metal or alloy layer. A surface of the superhard cutting table, is joined to the substrate by means of the metal or alloy layer which is positioned between them. At least a first surface of the metal or alloy layer and at least a first surface of the cutting table are co-operatively shaped with each other such that the co-operative shaping substantially prevents relative movement between the cutting table and the metal or alloy layer.
