"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 the 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 .160"" thick with drop point shape and includes a double thumb stud and kick for quick ambidextrous deployment and use. Combining the usability and construction of the knife with a durable VG-10 stainless steel blade make this folder a great addition to the Vulcan name.
