The Zwilling Bob Kramer Limited Edition Hand Forged Carbon Damascus Chef's Knife is used in a rocking method to mince, dice, and chop vegetables, herbs and more. This limited edition series consists of 170 individually unique hand-forged Damascus knives. Each knife combines the beauty and utility of Bob Kramer's design with traditional German forging and progressive German technologies. The blade is made of the purest, high quality, hand-forged Damascus steel that's handcrafted by one of the best blacksmiths in Germany. The steel combines two types of steel with different carbon contents, each contributing its own specific benefits. With a Rockwell Hardness of 61, this combination is extremely hard and sharp. The fire welding process produces a steel block with 160 layers, which is then forged by hand and hammered to the required thickness. The handle is made of Karelien Birch and precisely mounted with rivets and the prized Bob Kramer pin in the center. Includes hand-signed signature of Bob Kramer on the Certificate of Authentication. Each handle scale was hand selected by Mr. Kramer and finished by hand to ensure perfect comfort and control.
