A Blade Grinder is a basic tool used in coffee shops to grind coffee beans. Unlike more professional burr grinders, blade grinders are simpler machines that use spinning blades (like a blender) to chop coffee beans into smaller pieces. While they're not the preferred choice for high-end coffee shops because they produce less consistent results, they're often mentioned in entry-level barista resumes as they're common in smaller cafes or home settings. Understanding a candidate's experience with different grinding equipment helps assess their knowledge of coffee preparation basics.
