Benchmade took the Stryker and gave it a boost. With the new Nitrous assist opening mechanism, one of your most cherished knives just got better. The Nitrous mechanism is built directly into the titanium liners, which propels the D2 tool steel blade open with ease. Benchmade also upgraded to more tactile G10 handle scales for a great look and feel. The ambidextrous thumb stud brings this knife to life. The 912 and 913 deliver on what it means to be a Black Class knife.
