I could be wrong (and probably am), but I can't recall Spyderco ever putting Japanese specific steels into US made models? I believe it's due to Japan having export policies on their steel, again I could be wrong there, but I seem to recall reading that somewhere a while back.
If that is the case, we could try to get Sal on board for using Bohler Vanadis 30 on some models, or in a sprint/mule. It's basically their Hap 40 equivalent.
I would also love to see a LC200N Paramilitary 2.
