A simplified method of making and sharpening tools used in electrical discharge machining to avoid the laborious process of making a master die, a plastic master, several graphite blocks, a steel cutting tool and a final graphite block as a finished electrode. The present process uses a Surfalloy process wherein metal is deposited on a prepared block to have a sharpness characteristic equal to that of a finished steel tool. Thus, new tools can be made in about one hour where previous steps required about 90 hours.
