For smoothing and leveling defects we will use a sharpener with a granulation between 150 and 280, while the proper sharpening will be made with models up to 500. Above this number we are dealing with precise sharpening and polishing. Ceramic models have two levels of granulation , diamond can have even several. The most expensive sharpeners will be useful only if we use tools professionally and our maintenance depends on their sharpness. Less advanced solutions are enough for everyday use.
