The reason that I offered up 1084 is due to his being "new to bladesmithing" and all he would need would be a home made forge, a toaster oven, a file, some 1084 stock, canola oil and some charcoal.
Those items Should be much easier for him to scrounge up to attempt a first knife, given self HT (which I will concede wasn't specified).
What was meant by my "run of the mill" comment I that it is a relatively plain steel, it is not exceptionally high in Mn and Si, and it is a rather pure alloy. (For clarification, I would include 1095, AEB-L and other more pure alloys in a similar class of alloys, stainlessness withstanding).
If he was planning on doing his own HT, would you feel that 12c27 is as "beginner friendly"?
Just by including a 5-10 min soak without cryo at 1970 would negate other suggestions over 1084 stock, in which he would just have to nudge 50-75 over non magnetic.
In a position of doing a "backyard HT", as you know, 1084 is one of the most effective "beginner" steels. That doesn't mean it can't be made into a Nice blade, but simply that it is "easy" to start with.
If you misread what I had originally wrote, ease chalk it up to me having to be up for work in less than 5 hours, and I thought a more simple alloy would yield a more positive result from his efforts.

I am not trying to step on any toes, just trying to offer up an easier choice if he were to do his own HT.
