The Responder X9 is an exact replica of Mikkel Willumsen's custom work. The Sandovik 12C27 steel blade is designed to stand up to anything you can throw at it while still retaining cutting ability, corrosion resistance, and edge. The two-tone finish on the blade, black and green G-10 scales, curved handle with finger grooves, and stainless steel pommel with lanyard hole are all part of Willumsen's concept of functionality combined with urban aesthetics. The Responder X9 is designed for convenient carry and easy access.
