    Hey guys, I decided to strip my swamp rat chopweiler powder coat and have a question. I believe the steel is called sr 101. After stripping it, the blade has a gray tint to it, I would compare it to the color of a2 or 01 after I soak it in vinegar. Is this a patina on the swamp rat, or something different? I like the finish, but want to know if it will protect the steel like the forced patinas I normally put on, or is a vinegar bath still needed? Thanks

    I believe it is just sandblasted as it comes from heat treat.

    The Powder Coat was the Rust Prevention.

    I'd buff it out with some Turtle Wax. Ever seen a rusty turtle? Me neither.

    Turtles don't rust due to their high chromium content. Everybody knows that...

    If you dislike the finish, I would suggest taking the knife so progressively finer sandpaper (ending around 2k or so), then finishing with a Semichrome polish.

    Sometimes, powder coat is used to conceal a number of possible issues.

    I'd be afraid to look under *most*.

    FWIW, not all steel takes a decent polish but since this special steel is really (according to what I have found) 52100, with the proper materials, it can shine like a mirror.

    *Supposedly*, it is differentially heat treated, which means that if true, after polishing, you could etch it with nothing more than vinegar and *see* where it is hardened.

    Mike knows a lot about this than I do...

    I hate to be the only one to think this way, but IMHO, Busse puts a great coating on their blades, and there's absolutely no reason to remove it. It is a textured finish that should eliminate sticktion for one thing. The coating is hard and slick.

    Why would the coating bother you? You bought it like that. Why not just buy blades that aren't coated and save yourself the headache?

    Obviously, you are free to do anything you want to your knife, but you need to understand why they put that coating on in the first place.

    I know most guys here are not coated blade guys, which I don't understand. I don't believe the coating leads to more "drag", especially slick, textured coatings like Busse uses.

    I'm not just spouting off because I like Busses. I only have 1 that is coated. I only have a couple other blades with coatings, and I can't understand why it bothers anyone.

    You can buff those coatings as smooth and slick as you want. I mean that I have done this, and would highly recommend it. All coatings help keep your blade from tarnishing.

    I believe that the black coatings on other Good blades contain non-stick material like Teflon, or something similar.

    Seriously, try buffing the coating with white compound. In my experience, this leads to a very slick finish.

    Please understand that I am not trying to be definitive or divisive. It's just that, IMHO, there isn't anything "wrong" with coated blades, and unless you can provide data to back your opinion that there is any significant difference in performance, you're guessing. Buff the finish and give it a shot of silicone, and you will have a low friction blade.

    As far as looks go, do we care when we scratch the blade of a user? Again, my opinion, but an uncoated blade gets the exact same scratches. Since when do we care about an EDC that shows use?
    Trust me, for I like big butts and I cannot lie.

    It does cause more drag and I have handed identical blades - with and without coatings to a number of people and every one of them noticed the difference.

    Take a Coated machete and an Uncoated one with a nice satin finish and try it on Vines - Secondary Growth and Small Trees. chop some Downed Trees for firewood.

    The uncoated one will give better and noticeable results.

    Coated Blade Scuff much more than any satin blade and most satin blades just need to have the sap removed and they are good as new - Coated blades are Scuffed and Ugly after one use.

    Glad to hear you had different Results but I'll stick with mine.

    I'm guessing that there is no data to back your opinion that any coating improves performance of any knife.

    Reduce tarnish? Sure...as long as it lasts. Stainless takes damage and is *still* stainless.

    Just say'in...

    I did want to add that Jerry Bussee is a friend of mine and we don't allow anyone to bash him.

    He and I differ on the coating thing and he is certainly entitled to his opinion as am I.

    Either way, you should put Turtle Wax. I think we can all agree on that.
