4.1. Setting the sharpening angle
Before sharpening a knife, it is the necessary to choose the sharpening angle. The
sharpening angle chosen depends on the type of knife steel or purpose for which the
knife is to be used. The smaller the sharpening angle, the thinner the cutting edge on the
knife and, consequently, the sharper the blade that is obtained. But it should be
remembered that sharp blades are easier to damage when used, especially if hard
surfaces are cut. Thus, you have to nd an optimum angle that makes the knife sharp
enough for your needs, but not too easily damaged. Recommendations for the choice of
sharpening angle (in accordance with the type of the knife) are given in the chart below:
