The interesting case here is that the industry standard of milled grooves and laser surface roughness aren’t precise enough. So these wedges use extremely thin face plates, where the grooves and surface roughness are electroformed. In this method, the face plate is built up from liquid metal to tolerances as little as one-eightieth the width of a human hair. No less important, the metal used is highly durable nickel cobalt, so those precise grooves might just last longer, too.
