Slightly curved frets are mounted as each string and fret intersect at right angles to minimize the contact surface.
You can obtain accurate pitch, cleaner longer sustain and true harmonics.
*The frets we use aren't special. You can ask your nearest repair shop to hit them from the edge of the fingerboard when refret.
