The SWOTF9B is an assisted opening OTF knife from Smith & Wesson and the knife is super fast and well made. It has a safety and a tab on the side used to retract the blade in addition to the thumb slide. The mechanism takes a little getting used to, but it truly is an awesome and impressive knife. Built with tactical intent in mind, the SWOTF9B has a slender profile and a tactical black finish. The AUS8 stainless steel blade is 3.6 long and forged into a double edge dagger, very reminiscent of a Benchmade or Microtech OTF Automatic. The aluminum handles are contoured for a better grip and include a glass breaker pommel, a pocket clip, and a safety lock.
