Folding knives
Folding knives, such as the lockback knife or claspknife have locking mechanism such as a twisting ring or catch that must be released in a distinct action before the knife can be folded. This lock improves safety by preventing accidental blade closure while cutting. In contrast, slipjoint knives rely only on a small sliding spring to keep the blade open, and if enough force is applied to the back of the knife, the blade will close.
