How high of quality is the TiNi finish? I like the Super SOG Bowie but I don't like the finish so is there anyway to remove it?

edit:I am also wondering how easily it comes off and if it is just for looks or actually has a purpose. If it doesn't chip or scratch to much then I will keep it on.
 
All finishes will eventually scratch/ wear, even titanium nitride.

Okay, now how to remove it.

I know of two ways to remove a titanium nitride finish. The first is covered under US Patent 4877482 which protects a method for removing nitride coatings from metal tooling and mold surfaces without damaging the underlying base metal. It involves placing the nitride coated metal surface into a plasma reactor and subjecting it to a gaseous plasma comprising a reactive fluorine species. The reactive fluorine species may be derived from one or more of many well known gases. An optional step of cleaning the nitride coating is recommended.

Ooookay. Definitely not for the beginner.;)

The second way would be to contact http://www.tigold.com/

Tigold not only has the ability to deposit titanium nitride coatings, but we can remove the coating from your surface with no adverse effects to the substrate. From polish only, to complete refurbishment, Tigold can meet your needs in today's market.​

The TiGo technique removes the coating without disturbing the surface of the tool. With TiGo there is no loss of surface finish, no post removal polishing or buffing required, and it leaves a totally clean substrate.

TiNi is very hard (about 80 Rc, if I remember correctly) and lubricious. It's also corrosion-resistant.

Unless you can't stand the way it looks, I'd probably leave it until you scratch it up (which might be easier said than done). Then get it removed.
 
I would leave the coating on. I have seen several knives come through SOG with TiNi coatings that have been well used and the coating is still there and looks good. It does not chip or flake off, as it is not just a coating but actually bonds to the metal.

As JCaswell stated, it creates a much harder surface, has some anti-stick/lubricating properties, and adds some corrosion resistance. One other thing to consider is that removing the TiNi coating would void your warranty and we don't want that.

I've been pretty hard on my tech bowie for the better part of a year, and the coating has held up really well - no chips or flaking. Really impressed - its faired a lot better compared to the coatings on my BMs and spydercos. I'd leave it.
