I've only seen ONE Blue Point box in person. It was in a pawnshop.
I took time to mess with it a lot.
Don't know how old it was (couldn't turn it around to inspect the back) it was a much better box than most Waterloo boxes, or the rest of the lower end pack.
The roller action felt as good as a SnapOn, the metal may or may not have been quite as heavy as a low end SnapOn.
It was narrow but deep, with a matching top box.
Honestly, it had better quality than any but the top brands, like SnapOn, Mac, (older or high end Mac) Matco, Cornwall.
I would defiantly take it over my Sears Industrial for roller smoothness, overall feel.
I have seen Snappy boxes that were not any better. Entry level boxes, but with the SnapOn label.
