H-1 Tested very well in corossion resistance. Both in "Q-Fog" and I personally dove with one for a week, no rinse, no protection, no corrosion.
It is a Nitrogen enhanced (.10) stainless steel with .15 Carbon, 6.-8. Nickel, .5-1.5 Moly, and 14.-16. Chrome.
We were able to get good edges, especially with our serrations. Edge retention about in there with AUS-6, not as good as talonite, or dendritic cobalt, but quite acceptable for a steel that lives in salt water and much less expensive than the alternatives.
The Delica handle, with a modifed Delica blade (broader tip). Blade & lock are H-1, pins, clip, barrel are other very good salt water materials. We're still several months away. No prices yet. Should be a nice PC folder for those in and around the sea.
Not much else to say. I'll say more when we're closer to delivery.
