Duane Dieter and Jim Ray named their latest collaboration Mark Six Stinger. Mark Six, which is very similar in style to Mark Five, which once won the world's attention, is also an unusually gorgeous tactical straight-handled knife. Smaller than Mark V, with a total length of 9.35 inches (23.8cm) and a length of 4.5 inches (1 1.5cm), it has excellent knife holding ability. Glass-filled nylon handle has strong chemical corrosion resistance, high temperature and high pressure resistance, high temperature of 400 degrees Fahrenheit and good electrical insulation; The end of the handle is a handle cap made of hardened steel, which can be used as a hammer. Each knife is also equipped with a sheath made of pressure-resistant nylon material.
