Black T coating 1095or others to stop rust

[Nathan House]

I am using 1095 an I am looking for
a coating that is good to stop rust
I have no sand blaster so I would want one that sprays on and I can back in the oven
I know brownells makes one that sprays on
I would like to know how Mr birdsong
is coating his blades with the Black t or were I could get some,or is there any one who has some advice on treating 1095
to stop rust,coating etc.give me some input/

Hi Nathan, I dont have a whole lot of experience coating blades, but the Black T as Birdsong applies it is more complicated than a simple spray on finish. From what i understand it involves a chemical cleaning of the metal, then a bead blast treatment, then some sort of "parkerization" treatment, then finally the teflon finish is applied.

Ive seen several makers that bead blast there blades and apply a black oxide finish. This seems to help some, but its definitley not as resistant as the black t or any other actual "coating".

Ive never really had the urge to coat any of my blades, as i think the patina ages the knife nicely. If i want a rust resistant knife, i would use some sort of stain resistant steel.

Matt.

Nathan, I think you'll find that once you get a good smooth surface on those blades, the rust will just disappear, especially if you give them a good rub down with some light oil. And if it still bothers you, you'll probably find that going to a stainless steel is cheaper than the coatings. Most coatings are for cosmetic purposes.

If you want to coat them, you still need to get a good smooth surface before coating, because the coatings don't cover much in the way of scratches or other surface imperfections.

And BTW, bead blasting will make them rust worse. Anything short of a dead smooth, mirror polish will invite rust.

Correct that bead blasting will hinder rust resistance on a bare knife, but on a blade that will be coated, it gives something for the coating to adhere to, with greater finish durability as the final product.

Some of the 'wonder' spray on finished ive expereminted with have trouble adhering to smooth and especially polished surfaces.
