To understand why kitchen knives matter, start with the basic reality: a knife is only useful when sharp, and it only remains sharp through proper use and maintenance. Many home cooks and even some professionals treat knives as durable goods that require no attention beyond washing. In fact, a kitchen knife is a tool that requires the same kind of deliberate care you'd give to any precision instrument—a drill, a camera, a set of woodworking chisels.
