Since 1959, the M61 Vulcan and its derivatives is a 20mm 6-barrel Gatling-style rotary cannon that has been in service in many United States military aircraft through several wars. It fires standard M50 ammunition at 6,000 rounds per minute and is integral part of the armament of modern fighters such as the F-15, F-18, and F-16. Built upon the M61 Vulcan’s reputation of speed, power, and versatility, the SOG Vulcan is also formidable with a powerful strength of construction. There is nothing weak about the Vulcan. For instance, our patented Arc-Lock can hold over 1000 lbs. of force. The full steel liners encased in glass reinforced nylon (GRN) handles give the knife rigidity and durability. The blade is a full 0.16″ thick with drop point shape and includes a double thumb stud and kick for quick, ambidextrous deployment and use. Combining the durability and construction of the knife with a durable VG-10 TiNi blade make this folder a great addition to the Vulcan name.
