Good chef's knives don't come cheap, so you might be tempted to pick up a blade or two at the dollar store. Just remember that you get what you pay for. The reason good knives are expensive is that you're paying for quality—something dollar store knives are not known for. Safety is also an issue: Because dull blades are more difficult to use, they can lead to dangerous cooking accidents. You’re better off investing in a sharp knife that will last a lifetime.
