The W.R. Case & Sons Cutlery Company has a very rich history that began in 1889 when William Russell (“W.R.”), Jean, John, and Andrew Case began fashioning their knives and selling them along a wagon trail in upstate New York. The company has produced countless treasures and it continues to do so as one of the most collected brands in the world.
Back in the '70s, I purchased a few knives that weren't Stainless. Being too young and dumb about keeping them oiled and not knowing about patina ended up pitching them. Eventually, I would only buy stainless knives for years. Now that I "collect" instead of just "accumulate", Oh how I wish I had those Case, Belknap & Boker Tree knives today.
Non-stainless requires a bit on maintenance, plain and simple. Even then, you might get a spot or two. Nature of the beast. My favorite steel, next to older Case carbon steel, it Old Timer. I've got some old ones with a natural patina that look awesome. Great steel to work with and sharpen. Glad I've got several of them as they are now a whole different animal that arrives on a boat.
