What is SpeedSafe? A patented, assisted-opening system built into many of Kershaw's best-selling Ken Onion knives. SpeedSafe assists the user to smoothly open the knife with a manual push on the blade's thumb stud or Index-Open system. (Index-Open uses a protruding portion of the blade's finger guard to give the user an alternative to the thumb stud. The user manually pulls back on the protrusion with the index finger to open the blade.)
