Kasumi Hammered 20cm Chef's Knife is the main knife in the Kasumi Hammered series. A multi-purpose knife, it can be used for any kitchen task. Also comes in a 24cm version. The hammered pattern on the blades is the result of hot forging by hitting the blade repeatedly with a 300-ton flection machine. The uneven hammer design prevents food from sticking to the surface of the blade. Kasumi hammered knives feature an inner core of VG-10 stainless steel with an outer layer of SUS410 stainless steel. The core of Kasumi is hardened to over 60 HRC. The handles are made from POM material, ergonomically shaped to the hand.
