My favorite is the same as last year, today and tomorrow....carbon steel. I love for my knives to show their age. Just like me.
I agree with you but, isn't that a Buck 119 in 420HC stainless steel? It's very stainless in my experience, leaving my 119 wet and with organic materials on it, or keeping my 110 sitting in my food plate for a few hours eating a long BBQ dinner one night.
Still definitely shows it's age! It would be super cool to have a little run of these in an old school carbon steel (52100, 1075/95, Johnathan, etc) just for the cool factor and possibly a bit tougher at that hollow edge, besides I enjoy a good patina, myself.
As to the thread, I gravitate towards carbon steels. Cruwear, K390, M4....
I have had S45VN, S35VN, AUS 8, spot rust on me, BD1, BD1N, whatever Mora uses and 420HC are the only steels I would say, take out in the rain or fishing and expect to be unscathed not having to fight rust after. Note to readers, I do not do extended wet things, so I am sure 420HC is not the best choice for a fishing raft knife.
But some of my favorite models are just made in AUS10A, VG-10, XHP, 4.116 Krupp, (love SAK for sharpen/storability and ease) so... I appreciate stainless too.
