Embodiments are described for a simple convertible utility knife and scraper includes a handle, slide mechanism, and flat spring with a centrally mounted utility blade. The flat spring locks into precut positions in the handle to secure the blade in the desired position, whether in a cutting position or a scraping position. The blade can be partially extended to expose the front of the blade in the cutting position. When the slide is fully extended, the blade can rotate about a central axis to a position perpendicular to the handle and then be retracted into slots at the end of the handle to secure and support the blade in the scraper position.
