I have new ultima aspire xp blade's and they are freshly sharpened. Yesterday I had my first class and I mainly worked on my edges and after class I wiped off the blades and put on my soakers. When I came home I also dried the blades again with a towel and put them into soakers and put them into the corner of my room. This morning I pulled off my soakers and realized there are small brown like specks along the groove of my blade. I do not want to believe this is rust because these blades are so new and I have only used them once and also took good care of them as usual Do you think this is a major problem or something I should ignore
