Despite the review published on July 27, 2012 indicating that the Photo and the description working does not match the model number, the sending still does not match. Model #473 (which is clearly marked) has fewer blades and no locking mechanism, making it less desirable and less usable than other high-end products. It would be nice if the photo and description (including mentioning the ability to lock the blades) were updated so as not to mislead other buyers.
