Query: Great Deal - Beware of Substitutions

This is a fantastic deal. I am very pleased with my purchase, but beware of substitutions. I purchased two sets, one as a gift and one for myself. One set arrived as advertised, with a 3-in paring knife, 8-in carving knife, and 6-in cooks knife. The other arrived with a 3.5-in paring knife, 8-in bread knife, and 6-in cooks knife. They both seem like equally good deals, now I just have to decide which to keep for myself.
