At Edge Technologies, Inc., “the leading edge” isn’t just a slogan.  Our edges are chemically finished, producing the smoothest and most durable precision radius turning tools in the world.

ETI’s tools are manufactured with natural and synthetic single crystal diamonds that undergo a proprietary chemical-finishing technology which includes RCA and ETI patented equipment and processes.  Actual machining experience has determined our tools to be of the very highest quality.

ETI’s chemically machined edges are vastly superior to abrasively finished tools that are commonly available…  ETI’s edges have been documented by the U.S. Navy as nearly perfect.  Our edges are sharp and continuous at better than 10,000X magnification.
