The SOG Flash™ line of folding knives debuted SOGâs patented S.A.T.™ (SOG Assisted Technology). This mechanism helps propel the blade open once the operator has initiated the one-handed opening action. They open very quickly and lock firmly. The Flash series employs a powerful piston locking mechanism that can be unlocked with a sliding lever. It features durable and textured glass-reinforced nylon (GRN) handle for slip-resistant use. When not in use, the reversible low-carry pocket clip allows you to stow your knife securely and discreetly. Incorporated into the design is versatile safety lock that helps ensure the blade will not open while being carried. Available in a variety of colors, blade shapes & finishes, and sizes; the Flash series makes a great lightweight EDC.
