A scale will split at the pin like that if the razor is forced too hard into the scales. That is why so many bone and ivory ones have that crack at the wedge pin. Celluloid tends to be flexible and less likely to do that but it can still happen. If it was closed really hard or if it was banged around it could have cause that but if would have had to be pretty hard.

And this is my 500th post after the great crash. Smurf the crash cause I would be a blabber mouth now! But yea anyways!
