I am a good sharpener and whenever I use my knives I first, don't want to mess up my edge, and second, don't want to mess up the knife itself. I know a knife is robust and strong but the problem is, it doesn't matter how cheap the knife is, I never want to use it too hard. I have a question for folks on here: What would you say is 1.) Light Use 2.) Normal Use and 3.) Abuse? Just so I have something to reference or a rule of thumb. Thanks guys.
