The SR-22 is a smaller version of the SR-11 knife, which was an upgraded version of the popular SR-1 model. The SR-11 won the Most Innovative Imported Design award at the BLADE Show in 2010. The SR-22 has some improved features, including a flipper opening with a ball bearing pivot system. This system uses two ball bearings to make it easier to open and close the blade. The knife also has a tungsten carbide window breaker. Like its predecessor, the SR-22 has a Rotoblock system that keeps the blade securely locked in the open position. The knife has a single piece aluminum frame, which can also be made of titanium. The frame is made using 4-axis machining to provide a better grip. To prevent wear, the lockbar insert is made of stainless steel instead of aluminum. The knife has a deep carry bayonet style pocket clip that can be reversed for ambidextrous tip-up carry. Overall, the SR-22 is a well-designed knife that showcases LionSteel's commitment to constantly improving their products.
