Wusthof Ikon Blackwood - Gourmet Perfection. The Wusthof Ikon Blackwood series consists of various professional knives with a modern design that are completely forged from one piece of X50CrMoV15 stainless steel. Features a triple riveted wooden handle with a double bolster. While the standard position of the bolster between the handle and blade is an integral part of a precision forged knife providing heft and balance, the second bolster at the end of the handle completes the feel and ties in modern design.
