I bought this shirt for my boyfriend for Christmas, and he just wore it yesterday. I noticed there was a strip of ink missing on the knife, like it had already been worn off from frequent use or something. I know some shirts are stylized to look worn, but I don't think this one is supposed to...

Has anyone had this problem with this shirt or others? I've bought maybe 20 shirts and never had an issue with the actual design (have had issues with fraying and holes though...)
