The CRAFTER series from Wusthof features the same PEtec (Precision Edge Technology) as their other forged lines of cutlery. PEtec results in an edge that is 20% sharper with twice the edge retention than non PEtec edges. All CRAFTER knives from Wuthof feature triple brass rivets, with a new smoked oak handle. This process impregnates the handle and makes it more resistant to picking up food particles and odor from food. Hand washing is required, and these are not dishwasher safe. Backed by a lifetime warranty against workmanship defects. Add one of these beautiful knives to your kitchen today!
