An assisted opening knife is a folding knife that partially opens by pushing a thumb stud or flipper attached to the blade. When it partially opens (up to 45 degrees), an internal mechanism or a spring will then fully open the knife. It is the reason why it is also called a spring-assisted opening knife. This type of knife is commonly used as an everyday carry tool knife.
The best assisted opening knives are those which open in a shorter time, and you can carry around legally, unlike switchblades. A switchblade is a folding knife that opens automatically with a push of a button, thus considered illegal in the country. It is also called an automatic, a switch, or a flick knife.
