These beautiful pocket sculptures feature polished stainless steel handles, patented Arc-Lock, Abalone thumb studs, and authentic Stingray hide inlay! Despite it’s sleek and smooth exterior, the Stingray is still SOG tough on the inside, guaranteeing you will have the answer to many of life’s situations at your fingertips.
