I have a new 5/8 dovo prima klang, carbon straight. I just noticed two small blemishes on the side. Not near the edge but in the front middle of the blade. Could this 'rust' spots??? After use I clean and wipe the blade, and let it rest over night before I place back in the original box. I tried to clean off the spots but they would not removed. As I was touhing it up with soapy water it did bead up, so I think there is some oil on the blade. Any suggestions will be appreicated. Thanks Nick
