Spyderco’s Native® 5 Lightweight Maxamet® combines the highly refined form, function, and ergonomics of our proven Native 5 Lightweight model with Carpenter® steel’s state-of-the-art Micro-Melt® Maxamet blade steel.Maxamet is an extremely hard high-speed powdered tool steel possessing properties that transcend conventional high-speed tool steels and approach those of cemented carbides—the ultra-hard materials used to machine other steels. When Carpenter developed this amazing alloy for the rollers in their steel mills, they sent samples to various companies in the knife industry to evaluate as a blade material. Although many tried, Spyderco was one of only a handful of companies to successfully develop the specialized methods necessary to machine, heat treat, and grind this demanding material to yield reliable, high-performance knife blades. We are now proud to offer it in selected models made in our U.S. factory in Golden, Colorado.
