It doesn't say what the actual coating is, but I always thought that the BK was Boron Carbide, which is a very hard coating, and much like the popular DLC coatings we are seeing more and more of. The DLC coatings, like on the ZT's mentioned above, are very hard and things being cut are more likely to leave a streak/residue on the coating, instead of an actual scratch. The DLC coating usually has an RC rating in the mid to high 60's, or higher. Definately harder than the steel it covers. I also think that Boron Carbide has a similar RC rating.

But my question is; What is the coating that is identified as BK?


Edited to add;

Did a Google search on Cerakote, and then a search on cerakote being used by Benchmade. Came up with a lot of good info and it sounds like the Cerakote coating is a real improvement in coatings. I know I had gotten some pine resin on the blade of my new Adamas, and after wiping some off I used a product called mothers mag polish to get the rest off and it did a heckuva' job on cleaning the spot so that I polished the entire blade with it!!

Seems to be some really good stuff.

I don't know why they went away from it, as it was much better than the BK coating that replaced it.

Nothing else in the steel lineup requires any protection other than regular cleaning with your favorite, mine for example, being Tuf-Glide.

As Shadow says, there's no way to repair scratches in the coating. Live with it, strip it off, or buy satin finished models, which are a lot easier to keep good looking.
