We must recognize that the pair of scissors Wingman is inefficient (in contrast, that of the Leatherman Style CS is great). Nevertheless, Wingman scissors have a good spring that works by opening in until "click". To close, it's like the blade, you must press the "lock" icon. Otherwise, the blade opens with one hand with the thumb and that's good practice. The clamp to such spring scissors, which is not the case with all Leatherman (such as the Camo Fuse), excluding without a spring clip is like a shovel without a handle, it can be used but c is less convenient.
