Abstract
A folding hand tool with an open-assist mechanism that is not mechanically linked to a folding knife blade is disclosed. The open-assist mechanism is allowed to rotate around the same pivot used by the blade, and includes a lug that interacts with the kick of the blade when rotated. Because the open-assist mechanism is not mechanically linked to the blade, it has a range of free motion that promotes safety, and allows the mechanism to rotate into the blade cavity when the blade is extended. The folding knife also may have a carabiner that shares the blade cavity with the blade, with the blade nesting into the carabiner to save space, thereby giving the folding knife a smaller profile.
