This SDS Ultro model has a simulated carbon fiber body. The stainless steel drop point blade on this knife is two-tone black finished with a single edge. It is a double-action OTF knife with performance you’re sure to enjoy. This automatic knife fires open and closed with the slide of the firing button.
