What is an otf knife?

An OTF (out-the-front) knife is a type of automatic knife that has a blade that slides out of the front of the handle when activated. These knives are often used for self-defense, as they can be quickly deployed with one hand. OTF knives are typically spring-loaded and can be operated by either pushing a button or sliding a switch. They are popular among law enforcement and military personnel, as well as for everyday carry for personal protection. OTF knives come in a variety of sizes and blade styles, making them versatile tools for a variety of tasks.
