I own several normal pocket knives, and have sharpened them before. But this knife presents a problem for me. Not only is it my most expensive pocket knife but it's half serrated, and it has a black Ti-Ni coating. First off, how can I sharpen a half serrated knife? Secondly, and more importantly how can I sharpen it but not scratch off any of the black coating? Currently it looks pretty slick with it's consistent 1mm strip of shiny steel contrasting the jet black of the coating. Is it possible to sharpen and not ruin this?

Knife in question, SOG Black Trident Folder, SG-TF1:

any rod type sharpener will do for sharpening serrations and straight edges...I usually carry a small triangular rod (strapped to my seal pup) cause it can handle both the serrated and steraight edges...Ceramic, as far as I understand is mostly good for touch ups so the best advice would be to give it a quick touch up after each significant use and never let it get real dull
 
Sharpening any blade to avoid scratches requires a lot of care. One very good way for preserving the finish is to cover the blade (except for the edge you're going to be sharpening) with masking tape. Masters of Defense specifically recommends doing this when sharpening the XSF-1.

A half-serrated edge is really two different edges on one blade. They have to be sharpened separately. For starters, I'd suggest using Spyderco's Profile ceramic stones on the serrations, since the Trident has Spyderco style serrations (so does the Pentagon, btw). Once you've finished with the serrations, then sharpen the forward straight edge on a stone, as you normally would.

You might want to seriously consider buying a cheap black coated knife that is half serrated and practicing on that one first. If you make any mistakes there, it's not a problem. You'll be able to keep your Trident looking as sharp as possible for as long as possible.

One thing to keep in mind, just the same. All knives that are used regularly sooner or later get scratches. It's inevitable.
 
The serrations themselves are applied to only one side of a conventionally ground blade, if that's what you're asking. At least they are on the Pentagon, which has the largest length of aggressive Spyderco-style serrations of any SOG product. Lots and lots of teeth, all the way to the point. ;)

Ernest Emerson's site has a nice tutorial on sharpening chisel edges, and chisel edged serrations. Just select "knife sharpening" on the left index bar.
 
I just touched up the edge on my TF-1, and used the Spyderco Sharpmaker. They have good info on serrated blade sharpening, and if you follow their directions and are very deliberate in what you're doing, it works well...
