A cutting device and a method are designed to facilitate precise cutting and prevent a user from cutting fingers and hands. The cutting device includes a body and a lid. The body has a mounting mechanism, to which a razor blade is removably attached. The lid is pivotably coupled to the body by a spring. Moreover, the lid partially covers the razor blade so that at least one cutting edge of the razor blade is exposed. Thus, the cutting device safeguards the razor blade and protects the user's fingers, hands, and other body parts while allowing at least one cutting edge of the razor blade for cutting operations.
