I bought these to recheck the edge retention comparisons I did on dendretic cobalt and check the performance of Boye's serration pattern, plus I needed a nice locking efficient cutting knife and I was going to make a gift of the serrated one to my mother as an emergency knife for her purse.

However the serration pattern was not very aggressive at all, it was outcut several times over by the Spyderco serration pattern on ropes, plus the plain edge version was readily out cut by various folders like the Rat Trap and the edge retention of the cobalt was well behind S30V as well.

Anyway not a lot of work was done with these besides EDC on the plain edge for a couple of weeks and light work with the serrated version to check aggression and fluidity.

If you really need extreme corrosion resistance then these would be a good choice, but otherwise, something like the Military or Rat Trap would offer better cutting ability and much better edge retention and durability.

Does anyone know if Spyderco makes something like the Rescue folder in one of the really corrosion resistant nitrogen steels?

Thanks, has Sal commented before why they can get different relative performance on the plain vs serrated edges?

Not that I'm aware of. I've been considering getting an Atlantic Salt and happened to remember that thread. You might ask over in the Spyderco forum, it's an interesting question.

A couple of years ago, they gave away some extra dealer's videos, which showed the automated CATRA machines that are used to test and measure edge retention. Very cool.
 
I have the plain edged version Cobalt knife and it seems to just keep cutting and cutting, seems able to keep that more aggressive bite to the edge than other knives seem. Not for everyone, but when I need to cut something and not worry that it will slide over the material, I reach for that knife. Especially like cutting plastic tye-wraps, it cuts/saws right through easily.

In some thread somewhere, putting serrations on work hardens them.
 
Boye grinds a fine edge, very thin and acute, he also initially sharpens with a coarse abrasive. They slice quite well compared to most knives, easily outperforming most tacticals many times over. However if you compare something like a Military from Spyderco with a full falt grind which tapers to an equally efficient cutting profile, on a much harder steel, which you can also give an aggressive edge finish, the comparison doesn't favor the Boye. I prefer his 440C to the Cobalt for utility, unless you need the extreme corrosion resistance I would look for other knives. Spyderco's H1 is probably a better choice there in any case.
