I have such type of knife problem- where it's going dull because of galvanic corrosion! It's S30V with DLC coating and since there is Tungsten in the DLC coating- under the right conditions a galvanic element is created. The condition I have is a very humid environment, and even under the slabs (which are removable) where the humidity is trapped- the blade rusts straight through the DLC coating. So in your case, it could be that the S30V blade creates a galvanic element with something it's in contact with...
One other interesting detail I have found with S30V is that the S30V blades I have- all are magnetic... And I mean the blade acts as a magnet and I can use it to pick up screws etc. Not sure if this affects the corrosion and if it's normal....? I have not experienced this in any of the other stainless steel blades I have.
