[1] This mechanism of opening is fundamentally different from the switchblade , which extends its spring-propelled blade automatically upon the push of a button, switch, or fulcrum lever. [ 1 ]

2024年12月29日 · Gravity knives are as portable as folding blade knives, but they eliminate the hassle of trying to open the knife one-handed. In fact, they require no effort at all to open—gravity does all the work for you.

Gravity knives feature a mechanism (button, trigger, or lever) that allows easy one-handed operation with the assistance of gravity or inertia to deploy the blade.
