This Ken Steigerwalt design makes for a perfect EDC. The Nitrous spring assisted mechanism makes one handed opening a breeze. Give the blade a nudge and the knife does the rest! Release is nearly effortless, and the action is quick and the lock-up is Benchmade perfect. The BK1 black coated 154-CM blade has a right handed thumb stud and the knife body is black G-10 handles over steel liners. A lanyard hole and deep carry pocket clip (tip down) are also present.
