Ultrasound is used in various industrial fields, and ultrasonic cutting has recently attracted significant interest. With ultrasonic cutting, the cutting force is reduced, and the cutting precision and quality are significantly improved when cutting various materials, such as metals, non-metals, human bones, and food. Most studies on food cutting have focused on automated cutting systems and cutting tools using robots or three-axis linear motion guides; therefore, cutting tools that can be used manually in general households, bakeries, and food stores are required. In this study, we developed a cutter that can efficiently cut or process food by applying ultrasonic vibration to the cutter while maintaining a shape similar to that of the existing hand knife; thus, it can be used in grocery stores, bakeries, and general households. The vibration amplitude of the prototype cutter during the ultrasonic oscillation was approximately 36 ㎛, and the resonant frequency was 27,888 Hz, confirming the effectiveness of the prototype. When cheese was cut with the developed cutter, the cutting force decreased by approximately 34.5% on average compared with the case without ultrasonic excitation, and when cutting ham, it decreased to approximately 59.4%.
