I got an email from a diver about this thread who told me that my Spyderco Byrd Crossbill is the cheaper form of the Spyderco H1 Spyderhawk.
Evidently the H1 Spyderhawk is used as a dive knife.
According to him my Chinese knife will discolor over time and may have some oxidation maintenance issues whereas the H1 Stainless is completely rust free, not effected saltwater at all, and holds a superior edge.
He said they are basically indestructible.
Checked around and those knives can be found in the 60 to 75 dollar range.
Nice knife but I think I'll stick to my cheaper version
