I see both sides of the argument here, but it is like wood Vs Micarta Vs Plastic (rubber) Vs Stabilised wood in that we are all individuals (i'm not!) and so like different things for different reasons. I personally prefer carbon as i find it, and i don't know why i describe it as this, but, warm. It's a warm and comforting metal. I find stainless cold and impersonal, sterile if you will.
I feel a little bit like a wine bore trying to describe a flavour (Mmmm, tastes like boot polish on a rotting apple inside an old wooden school desk!) but that's the way it feels to me. carbon always smiles when you take it out of the sheath, Stainless always grimaces and says 'What are you F***ing looking at?'. Still, i've only played with cheap stainless knives (apart from an F1 but we won't go into that). Maybe when i get to have a butchers at Dougsters 'Special' i might change my mind!
