An OTF knife, also known as an out-the-front knife, is a type of knife with a blade that is deployed from the handle by a spring-loaded mechanism. OTF knives are known for their fast and easy deployment, making them popular for self-defense and tactical applications.
OTF knives have a number of advantages over traditional folding knives. First, they are much faster to deploy. This can be a critical advantage in a self-defense situation, where every second counts. Second, OTF knives are more reliable than folding knives. The spring-loaded mechanism is less likely to fail than the locking mechanism on a folding knife. Third, OTF knives are often more compact than folding knives. This makes them easier to carry and conceal.
