What are Automatic Knives?

Automatic knives are a type of knife that is powered by some form of energy source. This can range from a simple hand-powered spring mechanism, to a more complex motorized system. The most common form of an automatic knife is the switchblade; however, other types such as gravity knives and OTF (out-the-front) knives are also available. Automatic knives have been around for hundreds of years, but they have become increasingly popular due to their convenience and ease of use.
