I have two stamps like that and have used for about 10 years. Never had a problem with either one. Their for two different names i make things under one is used all the time and the other once in awhile. I don't take the best care of mine either, use it and pitch it back in the drawer. Neither one has never had any damage.
I'm not sure about different makers being better than the other. Mine came from Hide Crafters. I'm not sure who did the work for them. Or i'm guessing they had some one else make them.
