I like them and they're the only pocket knives I carry.
The medium Stockman has been my go-to pattern, and I have a couple of them. I have CV steel in yellow handle and amber bone, and a stainless(True-Sharp) yellow handle.
Lately I've been carrying a Trapper yellow handle/CV that I've had for a while. I also sometimes carry a CV/red bone Russlock, which seems a polarizing pattern but I like it.
I have several others, some quite old that belonged to grandparents and the like that I don't really carry but enjoy having. My carry ones mostly are recent production(last 10 years or so) that I've bought new. I like CV steel on the whole, and have a few that I've intentionally let patina(which combined with regular use seems the best for continued rust resistance). I've not ventured into any of their exotic products.
