Assisted Opening Knives | Spring Assisted Knives Assisted opening knives, also called spring assisted knives, use an internal mechanism to help deploy the blade after the user begins the opening motion. Unlike automatic knives, an assisted-opening knife requires manual pressure to start the blade moving before the spring-assisted mechanism takes over. This design gives assisted opening knives a combination of one-handed operation, controlled opening, and convenient everyday carry. Knife Depot offers assisted opening knives in a wide range of blade styles, steels, handle materials, sizes, and price points. What Is an Assisted Opening Knife? An assisted opening knife is a folding knife with a spring mechanism that helps complete the blade-opening process after the user manually initiates it. Depending on the design, the blade may be opened using a thumb stud, flipper, or similar opening feature. The key difference between an assisted-opening knife and an automatic knife is how the blade begins to open: Assisted opening knives require the user to manually begin opening the blade before the spring mechanism assists with deployment. Automatic knives use a button, switch, or other release to activate the automatic opening mechanism. Why Choose an Assisted Opening Knife? Assisted opening knives are popular for everyday carry because they combine convenient one-handed operation with the familiar design of a folding knife. Depending on the model, useful features may include: Thumb studs or flipper tabs for initiating blade opening Spring-assisted mechanisms that help complete deployment Locking mechanisms that help secure the blade during use Pocket clips for convenient everyday carry Different blade steels and profiles to suit different preferences and applications Assisted Opening Knives for Everyday Carry From opening packages and cutting cord to handling everyday cutting tasks, assisted opening knives are designed to be practical, compact tools. Their folding construction makes them convenient to carry, while the assisted mechanism provides an alternative to traditional manual-opening folders.
