Patina is one thing, rust spots aka pitting, quite another....
Patina is only really achieved by carrying one knife religiously day in day out for weeks to the exclusion of all others, constant use and constant wiping down. Turn your back and rust gets a look in. Then it can turn to pitting which you can't get off, this is really dismal on a relatively new knife. Let's look at this carefully, patina may denote 'character' slow time changes etc most people revere this, however, does not everyone also revel in a brand new knife straight from the box/tube? Yes. Otherwise there'd be no buying. Spotty, uneven patina is frankly ugly and it's a rust gateway as well. I've really come to the conclusion that I prefer stainless, it's simply more suitable and a whole lot less annoying. .Consider a high polish crocus finish carbon blade, looks beautiful, it then gets a few pepper spots on it ( just like that actually), value is diminished, you either endure it or turn it into a grey/black user-which has to be defended against further degradation. I suspect that a lot of the 'cult' of carbon has to do with some handed down idea that stainless is 'cheap steel' that won't hold an edge, that is for amateurs and the 'real' Traditional can only sport carbon out of respect for the past. Perhaps just after WW2 stainless was rather inferior and a poor relative but that is before most of us were born! I'm glad we no longer use carbon or plated table knives for sure plus all the other superior application of stainless steel in other areas, pocket knives should be included. Most Customs and Moderns use stainless types of steel, for good reason.
I'm not advocating that carbon should be disregarded or abandoned, far from it, but the fetishisation of it can be puzzling and confounding for sure. GEC's case is also a good one to consider, it very seldom produces stainless runs and even then very grudgingly. The ethos there is very clear, carbon is king, and the only legitimate king too. It is implied that stainless knives are not popular and that in the past they've remained shunned and unwanted on dealers' shelves for ages, I question this and suspect that it may be the choice of pattern that failed to ignite people. I'm certain that if a 50:50 run of carbon/440C knives were put out on the forthcoming run of 66 Stockman in identical scales, then you'd see both disappear fast. So too for any 81, 82, 25, 33, 92,38 run in stainless.
Rust or red spots turning up after only a few weeks carry is discouraging and more than irritating. Humid conditions or the sweat of a pocket generating rust is something that can change your mind about the total desirability of carbon. D2 is much better at resisting corrosion I've found, it will grey if you cut acid fruits with it but unlike carbon, it imparts no flavour on to foods. Then it stays sharp for so much longer than carbon can ever hope to achieve....
