The SOG PowerLock is used extensively in the Oscar nominated movie the Hurt Locker. Here is a screen shot from one of the many scenes that have the PowerLock in them.Also, if you look there are a few other SOG products in the movie. In my quick scan I saw a Trident and Gov-Tac.
Great movie! I noticed the Powerlock!
