That's not a knife, THIS IS A KNIFE ! That's the first thing I thought of when I saw this video. A guy walks in to rob the clerk with a knife and the clerk locks him in the store and pulls out a bigger knife. The thief finally escapes by smashing through the front door. The clerk than confronts him and his girlfriend who also has a knife in the parking lot. They take off but are arrested a short time later. It's good to see the clerk stand up to the dirt bags but you wonder how much it's going to cost to repair the front door.
