IMHO... having been seduced by the data that dendritic cobalt (e.g. Talonite) holds up well in salt water, I overlooked two issues:
1) there are parts in any folder which are NOT the dendritic cobalt, and therefore vulnerability to corrosion still exists and,
2) the rumor is (and I've sadly seen it once) that the dendritic cobalt blade.. though it can be scary-sharp.. can snap like a dry twig under minimal lateral force.
