Rust under scales

From what I have been told the coating, on coated blades, is under the scales as well to help with that. For satins I am not sure. I would assume there is an epoxy to help seal it but this is a very good question. Some HOG or Piglet will be along soon to give you a good answer I am sure.
 
The scales are so tightly compressed to the blade, the chance of even water getting in between is virtually nonexistant and let's say if it does, infi is very stain resistant. Rust just doesn't stick to that steel.
 
I've taken the handles off of a few of my Busse knives, and the ones that were uncoated (DCBB or Satin) have all had some kind of rust/corrosion spotting under the handle slabs. The rust wasn't very hard to scrub and sand off, but if you're not removing and replacing the handle slabs the rust will more than likely build up. The only way the pressure of the tube fasteners' installation will keep water out is if all contact surfaces are absolutely flat and/or match up perfectly around the edges to make a tight seal. From what I have seen this is not the case. I have to add the disclaimer that I live in Hawaii and we tend to have a bit more salt in our air than most of the country so that could be the reason for my corrosion experiences.

You can take them off, but the company will charge you to reattach them. Or you can swap the tubes for something like Corby bolts.
 
Rust can get under the handles just like it can get under the coating. If the coating is not a true vapor barrier, the rust will migrate between it and the steel via capillary action (wicking) since the edge of the knife is not coated. In carbon steels this can be a problem in stainless steels and steels like INFI it isn't much of a problem. All coatings provide some protection to rust because they limit oygen, but only true vapor barriers actually stop corrosion. Not sure what the coating Busse uses has in it, but if it is a vapor barrier then it will do it's job well.

Walter Birdsongs Black-T coating is a true vapor barrier. The Black Ti (titanium) coating is not a vapor barrier, it is an abrassion barrier. So you either get toughness with a coating or you get rust protection but a coating that does not last long and comes off easily.

If you have a steel that is not coated at least you can see the rust migrating and keep it off.
