Im familiar with this particular problem. This was one of our grooved steels. In the last year or so we have replaced two grooved steels due to rust. In both cases, (including this one) the environment was the major contributing factor.
Our steels are case hardened. The core of the rod is encapsulated in a casing hardened to rc62-65. The casing is relatively thin. Breaks in the surface as you would find in a grooved steel may allow moisture to affect the unprotected core under extreme conditions. Keeping the rod dry and oiled will solve the problem.
On the other hand, our smooth steels are completely impervious to moisture, they will never rust, and the only way to make them susceptible to rusting is to break the surface with a diamond cutter. They dont require oiling at all.
Using case hardened steel is really the only affordable way we can keep up with modern knife making technology. The emergence of super hard steels that are not brittle and will hold an edge longer is a marvelous thing. Figuring out new ways to keep these knives honed and sharp is a bit of a challenge- but thats what we do, and most folks are pleased with our efforts.
As a matter of fact, we have developed a ceramic/steatite rod that will appear on our site in a day or so that will hone any existing knife steel.

The author of this thread is a very likable fellow, and a good customer. At first reading of his post it appeared a bit negative, but I dont think it was malicious.
Of course I have no choice but to respond and explain, thanks for reading.
