Spyderco’s steel chart (PDF) provides detailed information on the chemical composition of the many steels we use in our knives. This allows convenient comparison between steels and enables you to better understand blade materials that have similar or vastly different qualities.

Spyderco was one of the first knife manufacturers to include comprehensive information on our blade steels in our catalog and on our website. As we pushed the envelope to feature more high-performance steels in our knives, we also expanded our efforts to educate our customers about those steels. Over the years, we published our steel chart in a variety of different formats, including everything from pocket-sized references to laminated brochures to posters.

Ultimately, we developed the interactive Steel Chart on our website, which allows the quick, easy, side-by-side comparison of multiple steels and the elements they contain. This handy tool, along with the detailed explanations of the effects of each of the alloying elements provided on our Steel Elements page, is one of the best ways of developing your knowledge of blade steels and their unique properties.
