I haven't been blown away by edge performance on the Nitrogen steels that replace carbon. So I feel the future is in steels that take advantage of having both.

Maybe in 10 years we can get something like a S90VN with a Nitrogen boost and higher working hardness.
That would be great.

Where can I find this post? Does he have a website or is it on a forum? Thanks.

The only way nitrogen could form an ammonium ion (NH4) is if it corrodes out of the steel matrix. This would mean a limited time benefit as the nitrigen dissolves away, leaving a nitrogen poor surface. If the steel has reduced chromium because the maker determines the nitrogen makes less chromium required for corrosion protection, the loss of nitrogen would result in poorer corrosion resistance than it would have otherwise had.

I have some of the Yaxell Dragon Kitchen knives. BD1N is good stuff. It isn't near rust proof in the way H1 and I imagine LC200N is, but rust shouldn't be a big concern if it is treated like your typical stainless knife. It's pretty amazing what a little nitrogen in the mix does. 14c28n is another eye raising budget nitrogen steel.

Here is a test of a Yaxell made Red Dragon Gyuto from Apogee Culinary Design.
