This is not what I would consider a warranty worthy issue. I read your post and I still don't understand what i am supposed to be seeing. I don't see any chip. I would advise you use the knife instead of worrying about stuff so small that people cannot even see it or that you might not understand the intended purpose. Looks like a tang ramp on the locking interface area. Keep in mind, this is a production knife, not a one of a kind handmade custom piece. There is always going to be some variations in manufacturing due to machining and handling during assembly.
