Sorry if this is the wrong place to ask but I was wondering if anyone knows what metal the liner lock is made of. The 599.

I had the 599 last year... after pre-paying for it... waited four months for it from "that web site" which was an absolute abysmal experience.
After I received the 599, I sold it several weeks later.
The scale under the clip had to be sanded down as both scales come literally rougher than coarse sandpaper, un-sanded the scale would have shredded my pants quickly.
From my personal experience, the worst aspect of the 599 was the fact that the pivot was
insanely tight... lubricating several times had no effect, loosening the pivot screw still had no effect... in fact, even after
removing the pivot screw completely from the knife... the pivot remained unacceptably tight, that's right.. even with the screw completely removed!
Finally in a last attempt to to loosen it, I took the 599 completely apart, lightly sanded every single contact point with fine sandpaper, re-assembled the knife and absolutely no change, the abysmally tight pivot remained.
To have a 'flipper' on the blade together with the Emerson Wave feature is pointless if when the 'flipper' is pressed.... nothing opens because the pivot is too tight.
The only positive thing about the 599 is that the Emerson Wave worked.
So to answer your question, unfortunately I don't know and the fact that the answer isn't given anywhere on the internet.. including the one site that hawks it says a lot in my opinion.
