Our daughter is doing a part time job where she gives presentations online to sell Cutco knives. I've seen the price of the knives and they are very expensive. With their guarantees, it seems the knives would be worth it for someone who uses them for work, such as a chef or cook, but are they worth it for everyday home cooks? I'm asking because it seems our daughter might be wasting her time by not targeting cooking professionals, but she doesn't know any professional cooks to sell to.
