   I think that while "sharp" is perhaps a finite term in actual   
   practice, assuming that one actually uses the knife, is more of a   
   relative term as if one is, for example, cutting meat all day, then   
   perhaps "sharp" is less important then "how often do I need to stop   
   and sharpen my knives?
