What type of edge does an endscraper typically have?

An endscraper typically has a steep working edge, which is designed for specific uses in tool-making and functional tasks. This steep edge allows for efficient scraping motions necessary to process materials such as hide or wood. The design of the endscraper is optimized for tasks that require precision and control, and the steep angle provides leverage that is advantageous when applying force during scraping. This tool is common in archaeological finds and is associated with various prehistoric cultures that required effective means of working with natural materials. The other choices describe edges that do not possess the functional characteristics necessary for an endscraper, which is specifically utilized for its sharp, steep edge to achieve its intended purpose.
