Black coating on Lum Tanto Folder?

[KnifeDude]

Can anyone tell me what the coating is that is on the Lum Tanto Folder. Aslo do you know if Spyderco will send out clip screws. There is a stripped screw on my knife. It came this way from spyderco

Dude,
If I remember well the coating is titanium nitride based. About the screws – the right place to ask probably would be SPYDERCO Customer Service.
