I would think the concept of "Antique" would be defined by the type of thing being described. An antique flower may be 2 days, steel pocket knife 25 years, steel trapper 10 years, stainless pocket knife 50 years, and a stainless diving knife 5 years and the like.. The condition of the knife is not considered but the quality of the item would affect or determine the condition of the knife when it has reached the antique stage. The whole concept can get quite muddy. The idea of "Vintage" would be determined by it's presence at or involvement in the emergence of the field the item is in. A modern survival knife may be "Vintage" to the survivalists but could never be called "Vintage" to knives in general. This brings up an interesting concept. "Vintage" items tend to be of less refined technology and quality than the perfected stages that come later which would limit their potential for becoming "Antique". It's just a mess aint it.??

According to an article I found on Martha Stewart's website, "antique" would be anything 100 years or more old.  Vintage usually describes anything no longer in production, but can be anything short of that.  Here is an example.  This is an original Remington bullet knife, model 1253.  It was produced close to 100 years ago, in the 1029s to the early 1030s.  It is close to being an antique.
