Sog BBA-99 Blink. Blink and you just might miss it. This robust little knife cuts with theâ big boys and features a reversible low carry clip. At its well-mannered price, the Blink is the gentlemen's knife with a naughty attitude. The Blink represents the best of both worlds, combining the proven design of the lockback with lightning quick blade access. Thanks to S.A.T. (SOG Assisted Technologyâ„¢), the blade is propelled open once the operator has initiated the one-handed opening action. Invented by Spencer Frazer, who always manages to come up with something different!
