Berkel San Mai Kitchen Knife 30 cm. Maple Handle. Japanese Stainless Steel HRC 60 Blade. Made in Italy. From the age-old tradition of Japanese Samurai swords. Already back in 1100 expert Japanese forgers combined different materials to confer superior and unprecedented cutting potential potential, resistance and flexibility upon Katana swords. Inspired by this tradition, Berkel has created its own series of Japanese SanMai steel knives. The blade consists of a central layer of extremely hard VG-10 steel, which maintains sharpness over a long time, and two outer sheets in stainless damascus steel, with 33 layers per side, for greater resistance to corrosion and torsion. Blade 7.5". Overall 12".
