Wusthof Classic 22.9cm Double-Serrated Bread Knife. 4152-7/23. Cutlery. Well known German quality and cutting-edge technology are brought together in the Wusthof Classic knife series. Wusthof Classic knives are forged from one piece of specially tempered, high carbon, alloyed stainless steel to ensure outstanding strength and sharpness. Classic series knives were the first to feature Wusthof PEtec - Precision Edge Technology - for an easily maintained razor-sharp edge that retains its cutting performance twice as long as other knives. The attractive, ergonomic black handle is designed for comfort and control, and is made of a seamless, synthetic material for a hygienic grip. The handle is triple-riveted to the full-length tang for exceptional durability and the full bolster protects fingers from slipping. The Classic 22.9cm double-serrated bread knife is specially designed to slice through breads with even fewer crumbs than a standard serrated bread knife.
