And there's the rub. What constitutes proper care, and when is it just not worth the bother? The thought of pulling out my knife rotation every single night, and coating all of the the blades with oil sounds ludicrous to me. Most of my users have 3 to 4 blades. That's not me owning the knives. That's the knives owning me. I just got lucky yesterday, that I had a 2-blade and a single blade knife left out. The two GEC knives had carbon steel liners, which also rusted.
And my pile of users changes from week to week, sometimes day to day. It's just too much upkeep for a reasonable person, IMHO. If I only owned one or two knives, it might be okay. But I'm not that guy.
