Abstract
A utility knife is provided with a feature of easy replacement of the blade and a characteristic that the utility knife body halves are prevented from separating from each other. The utility knife has a safety lock which is able to enhance the assembly between the body halves, such that even when the release mechanism of the knife is accidentally operated or the knife accidentally falls to the ground, the knife body halves are still securely attached with each other.
