Well, depends on the objectives of the collection. If it is size then yes you're right. But if it's the historical significance and creative engineering. Then the size is actually not big. I have only about 150 razors. I compiled a list of razors to acquire and it's about another 150 razors over the span of 15 years. Just to give you an Idea about size. Renzo Jardella has 8000 and David Grant has 1200. My collection right now is not even 2% the size of Jardella's. And when completed it will be 3.5% of his. And that's in 15 years from now.So I guess those rules only apply after acquiring a massive collection
