Method of attaching a stainless steel blade member to a support member of cold deformable material, wherein the imperforate blade member (5) is located in a die cavity adjacent a die surface having a through hole (10), the support member (6) is located in the cavity over the blade member (5), and is impacted to effect piercing of the blade member. The slug (7) of blade material displaced into the through hole remains attached by a radial tab (8) to the remainder of the blade, and then the slug is impacted to form a rivet head from the support material which has pierced the blade. |
