At last, fine grit (4000 to 8000) is like sharpening steel and is utilized to refine your knife’s edge.

2. Straight, serrated and double bevel notches

If you like to own different styles of knives in your kitchen space, then make sure that the electric sharpener you select must have separate notches for straight, serrated and double bevel knives.
