Care and proper use of a high-quality knife is always essential to maintain the best cutting edge and to insure the highest possible degree of safety when using. After all, a dull knife is a dangerous knife. The more pressure required to cut with a knife the greater chance of an accident occurring while it is being used.

Ideally, the knife should be sharpened daily (for professional cooks) or about every six months (for hobby cooks), and by the same person each time or with the help of a ‘sharping guide‘. Each person has an individual angle at which he or she sharpens the knife.


200 – 240 – Coarse grain – For pregrinding of dull knives or smaller repairs.
