Double cut vs Combat grade, which one rusts faster?

Excuse my noob question:

I'm considering one of it and will use it for chopping rainforest vines which sap can be acidic and tough to remove even with the dish cleaning abrasive.

Thanks

First, a disclaimer: Sometimes combat grade isn't different from double cut. Jerry differentiated the NMFSH models as NMFSH Combat Grade, NMFSH Double Cut, and NMFSH Limited Edition. The BOSS Jack Combat Grades however included both coated and double cut finishes. I'm assuming you're talking NMFSH here, though, because who isn't :)

Double cut definitely rusts faster, simply because it's not coated. Jaxx also never stores his double cut blades in leather because one of them rusted really badly on him that way. Sometimes you get a piece that's more rust-prone than other double cut blades too, presumably because bead-blasting machines can be inconsistent and unpredictable.
 
CG has a protective coating (except for CF/Competition Finish). DC is uncoated so it is more likely to rust imo.
 
Is this a real question you are asking?
What would rust faster, a painted car or an unpainted car?
 
I would go with the coated blade over a satin or double cut finish in those conditions. It will help to prevent rust except on exposed surfaces (i.e. the edge until the rest of the blade starts wearing down from chopping). If there is any rust on the edge, a simply sharpening should remove that with no problems. The combat grade finish is strong and durable and seems to wear really well.

Mate,

I was really asking the question from the noob side.Had a brief read up on the CG and DC.
Looks like a CG is better. Thank you for the tip.

I spent a year in Missouri, my car got rust UNDER the paint, bubbled right up. So ya, you tell me. :p
 
The coated blades are less likely to rust, but I like the color of steel. the trick is to keep a coat of oil and clean your blade. For a blade you plan to beat on though, I've noticed the coating does come off then you have a blade surface that is rough and likely to rust at that point. then, you can send it in to busse for refurbishing.
 
Coating gives you the ability to not have to worry about getting a blade cleaned up right away. If I were going to use a knife in the conditions you have presented I would go with coating.
