Abstract
A multi-locking utility cutter has a shank, a blade and a slider. The shank has a guiding groove having multiple first locking units. The blade is slidably mounted in the shank and selectively covers the first locking units. The slider is connected with the blade and has a second locking unit. When no external force is applied on the slider, the first locking unit and the second locking unit are engaged with each other to provide a locking effect to the blade. When the slider is forced, the second locking unit is disengaged from the first locking unit, such that the blade can slide. A locking position between the first locking unit and the second locking unit is located at the guiding groove of the shank, such that a locking force can be uniformly distributed on the guiding groove of the shank. Therefore, the guiding groove can be forced uniformly and the locking effect can be increased and improved. Further, the first locking units are covered and avoid exposure to the exterior environment to prevent damage.
