This is not correct. Overall quality and price point for razors manufactured over the last 150 years or so are generally well documented, and there are more everyman cheapo razors floating around on the market than heirloom collector's items. Having done restorations on both types I can tell you "cheap" razors typically shave just as well (or better) than heirloom pieces. Also it's substantially more likely that a "good" razor would have been used to death due to hone wear.
