The SOG Vulcan Spear Point Folding Knife is formidable with a powerful strength of construction. There is nothing weak about the Vulcan. Take for instance the patented Arc-Lock. Or, the full steel liners encased in glass reinforced Zytel handles. The blade is a full .160 inch thick with spear point shape and includes the new kick deployment of the blade. Press on the back of the blade and the knife comes out fast. Reversible clip, Arc-Lock, and double thumb studs make for complete ambidextrous use.
Vulcan = Heavy Armament.
