Strider used to send their S30V blades out to Paul Bos for the HT years ago. They broughtt the HT process in-house a while back but still use Paul Bos' recipe, considered by many to beone of, if not the the best S30V HT in the industry. Frankly speaking in my humble opinion, Strider S30V might possibly be the best S30V on the production market today. Unless you can get into a small run of some other high end, special steel from Strider, I'd choose their S30V almost any day of the week. And you'll know what I mean the first time you put their S30V to a rod.
As for S35VN, that is probably more in the category of typically HT'ed S30V and was intended to be an easier to machine, close equivalent to S30V but I'm not sure if the outcome was exactly as expected or not. I still prefer S30V at 60 HRC over any S35VN.
Ran hard, like 62, CPM-154 is good stuff but in the 58-60, I'd still take the S30V from Strider over it.
One key element is Strider has probably done more S30V with Paul Bos' recipe than any other steel by a HUGE stretch in their knives.
Strider S30V FTW as a general rule with Striders from my perspective
