The Volquartsen Exact Edge Extractor is manufactured through an EDM process to produce exacting tolerances. The new extractor will not lose its edge under impact such as other extractors made from stamped steel or titanium that will have their edges roll over and actually cause extraction problems after a short period of use. Our extractor features a very precise hook point. The Volquartsen extractor features a very precise hook point which is hardened to a RC 58-60 to withstand years of use and still maintain its edge. Volquartsen is able to hold the tolerances to +/-.0001" by utilizing the EDM manufacturing process. The hook is .005" closer to the rim of the cartridge to allow for the most positive extraction available.
