The Rainbow Blink brings the classic lockback design into the 21st century. Thanks to S.A.T. (SOG Assisted Technology), the blade is propelled open once the operator has initiated the one-handed opening action. Invented by Spencer Frazer, the Blink is the fiendishly simple gentleman’s knife with a naughty attitude. The reversible money clip can be used in either left or right side pockets for low-carry or securing dollar bills and cards. Also included is a small safety that helps insure the knife won’t open until you’re ready. The safety can be engaged once the blade is open so that the locking bar cannot be released. So, in essence, you have two locks.
