As shown in image ①, place your index finger on the back and move it forward while shaving the fret sides to round the edges. Gradually lay the file down and proceed with the work while carefully checking until a thin peak line is formed. Observe from the side to see if it has a beautiful crown. It's easy once you get used to it, but it's important to learn how to shave without making a triangular mountain at first. Marking with an oil-based pen beforehand makes the peak line easier to see. ☆ It bends moderately, making it easy to correct the bulging peak line. Image ③ The opposite flat surface has the edge left, so It is convenient and easy to use for fret side shaping and deburring. ◇ We recommend protecting with stainless steel or plastic protective plates. If masking, it is recommended to work with 2-3 layers.
