The present invention provides a method of making a metallic shield for shielding an edge of a component e.g. an aerofoil component such as a gas turbine blade or vane. The method comprises: providing a mandrel with a mandrel edge having a shape conforming to the shape of the component edge, wherein the mandrel edge comprises a surface having a width, W1; providing a metal wire having a substantially triangular radial cross-section with a base surface of width W2, wherein W2 equals W1; aligning and affixing the base surface of the wire on the surface of the mandrel edge; electro-depositing metal onto the mandrel and metal wire to form the metallic shield comprising the deposited metal and the metal wire; and removing the metallic shield from the mandrel.
