The Joker OTF Knife has been a popular out the front knife for over five years. This single action OTF fires out fast and hard. The lock up is solid. And the price is unbeatable. At under $30.00, this is a well built knife that is going to last for a long time.
Interesting notes about this knife, it was originally designed as a Special Forces combat knife. It is also a clone of the knife that Heath Ledger used while playing the Joker in one of the Batman movies.
