I guess if you prefer nicer knives, you could always buy new ones periodically and give the old ones away on buy nothing to someone who will take care of them.
In practice people will never use their knife sharpeners, and instead use horribly blunt knifes for years on end. They're better off buying new cheap knifes every year.
