There is nothing weak about the Vulcan. It is formidable with a powerful strength of construction. SOG employs their patented Arc-Lock™, which has been tested to over 1000 pounds of force at the lock, and full steel liners encased in glass reinforced nylon (GRN) handles. The blade is a full .160" thick with spear point shape and includes 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.
