does this finish scratch easily? does it have any advantages over satin finish? is it better than satin? thanks for the info!
 
The stonewash finish is bare steel.... stonewashed on the flats of the blade and satin/belt finished on the actual grinds.

"Satin finish" is actually a coating over the bare steel. Not sure what it's composed of... it's fairly scratch resistant, but I always prefer bare steel over any type of coating.

A stone wash (tumbled) finish will stay looking new for a much longer time than a hand rubed or belt satin finish.
A tumbled finish is actually just lots of little scratches on the surface so it hides sratches really well.
A satin finish is lots of scratches going in one direction so any additional marks show up easily.

I don't know which you would call "better" but they are both just fine for a knife. :):thumbup:

Continuing the thread - How do you think the teflon finish compares to the stone wash for durability?

That's a bit of "6 and half a dozen" The coatings obviously protect the blade very well. The places where the coating rubs off tend to be high traffic areas any way so you don't get much in the way of problems with rust.

A satin finish will get scratched up and look used pretty quickly. A tumbled finish will look pretty much the same for a long time, but both are more prone to oxidation at the areas that don't see much or any wear (like grooves in the thumb ramp, bits of the blade round the thumb disk) than a coated blade. But a stain or tumbled finish can just be oiled and is also fairly easy to re-do if you had to, so you can keep ontop of those problems with out too much trouble.

The whole blade isn't stonewashed. Just the flat part. The bevel has a satin finish. Very nice.

I believe that the original satin finish is CeraKote, which is not bad at all.

Good call!

From the Emerson FAQ:

We are currently using what is called a ceramic finish on our blades. The trade name is Cerracoat. It is used on automotive parts like racing headers. This baked on finish provides good corrosion resistance and high lubricity. it is hard and durable yet it will still scratch just like the blued surface of a gun. The coating will wear away with use, over time, and if you cut extremely abrasive materials it will scratch or wear more rapidly. Our warranty does not cover scratches or wear on the blade.

Pretty tough stuff. I'm glad Ernie moved to this from the older bead-blasted finish. A definite improvement!

The ceramic coating IS what many people think is a bead blast finish.
EKI has stopped using a coating all together for the satin blades and they
now have a belt satin on the bevels and tumbled finish on the flats.
 
My understanding was:

Bead-blasted [very early in production] ---> "Satin" [Cerracote] finish ---> Stonewashed finish
