The knife sharpener is a total of only 14cm long, of which the red plastic handle takes 5cm. So stay 9cm grinding face left. Diamond Sharpener usually cause a strong erosion on the cutting edge, so you should leave the cutting without pressure and without haste glide over the grinding surface. Without haste also because the fingers are protected from the blade only by a nearly 1cm high thickening the front of the red handle. Although the surface of the knife sharpener feels not rough, meet four five gentle strokes to a cutting back to give new focus. I have been pleasantly surprised by this little tool.
