This knife in that Japanese style is recommended for dicing all vegetables.
F.A Porsche worked alongside the famous Austrian chef Joerg Woerther to create a modern masterpiece, its ergonomic handle is just one of the reasons this knife has won countless awards. The handle of the Type 301 by F.A. Porsche is constructed of 18/10 stainless steel, and the blade is made of high-quality Japanese 301 steel. The blade of each knife is carefully sharpened by the hand of a knife master and a special grinding method is used, so the knife stays sharp longer and is easier to sharpen in the kitchen
Please note the following instructions to insure the knife remains in optimal condition for years to come:
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. Each person has an individual angle at which he or she sharpens the knife. The blade of the knife becomes sharper each time it is sharpened in the same manner, by the same person. Read the instructions included with your whetstone carefully. Sharpening with a 301 whetstone is so simple that even beginners can quickly master the technique required.
Knives with a serrated blade, such as the bread and tomato knives, should only be sharpened by a certified professional.
