My Gladius arrived today, and words can barely express its awesomeness

However, I noticed some rust on the Busse logo! This is straight out of the cardboard sheath - I cleaned the edge with isopropyl to get the leftover coating gunk off, but this part of the blade is untouched.

None of my other Busses have this rust on the logo. Has anyone else seen this? Is it a common occurrence? Should I be worried?
I'll get some more photos of this beast in the morning when the light is better!
