The SR-22 is the smaller brother to the SR-11 which was the evolution of the historic SR-1 model and winner of the Most Innovative Imported Design at BLADE Show 2010. The improved design features include the flipper opening with ball bearing pivot system - two ball bearings facilitating the opening and closing of the blade - and a tungsten carbide window breaker. Moreover, as its predecessor did, the SR-22 features a Rotoblock system, which blocks the frame in the open position allowing the user to use the design without fear of unlocking the blade, no matter what. The single piece aluminum frame is a unique piece, which is also available in titanium, completely worked with 4-axis machining for additional grip. The replaceable lockbar insert is made of stainless steel in order to avoid wear of the aluminum frame body. The deep carry bayonet style pocket clip is reversible and can be mounted on both sides for ambidextrous tip-up carry. This is an excellent design showing the continuing improvements LionSteel makes to their products to always keep on the cutting edge within the industry.
