[ What is claimed is:] [1.] A method of manufacturing a mechanical fastener from a replication master tooling article, comprising the steps of:providing a flexible, thermoset polymeric tooling substrate having a low energy first surface;machining to remove material from the first surface of the tooling substrate with a laser light source to produce at least one geometric structure having at least one side surface extending from the first surface of the substrate into the substrate, thereby yielding a replication master tooling article for manufacturing a mechanical fastener;applying a moldable material to the first surface and geometric structures of the replication master tooling article;at least partially solidifying the moldable material to produce a mechanical fastener; andremoving the mechanical fastener from contact with the replication master tooling article.
