I voted S35V, but if Bladite says that ain't gonna happen, I'm inclined to believe him.
The choices in the poll are all good, but don't be fooled by the way the vote is shaping up. Yes, 1095 is ahead as the single most popular choice, but it's still only at about 30%, which means that 70% prefer a different steel. That puts 1095 in the minority, depending on how you look at it.
I have a lot of positive experience with S30V, none with S35V, though my understanding is that there's not enough difference in composition or characteristics to really draw much of a distinction between them. Assuming that's true, that's why I voted S35V. Awesome blade-steel.
I also have a lot of experience with 154CM, and agree, it is a very good blade-steel. Probably cheaper (though I'm not positive about that - I see a lot of customs made out of 154CM that are just as expensive as any other medium-to-higher-end steels).
If people are shying away from S30V (or 35) because of cost considerations, there's no way ELMAX or M4 is going to suffice. Though I have no personal experience with either, I have read up on them a lot, and yeah, they're both awesome blade-steels, but e.x.p.e.n.s.i.v.e.
I personally have no problem with D2. I've used it and been satisfied with it. I think the charges of brittleness and lack of toughness are overblown when talking about using it for knife base material. The comparisons are usually tested against other tool steels in their role as tool steel, not knife steel. Tempered right, D2 makes a great knife steel.
With the exception of the D2, all of the experience I allude to above has been with using folders. That is a limiting factor in how useful my experiences are to the question at hand. I'd have to see some data or personal experience saying that S30V (or 35) is deficient for some reason in a fixed blade before I'd be wanting to change my vote, but since that ain't gonna happen anyway (according to Bladite), I'll go with 154CM or D2. For me, in a limited run scenario exclusively for BFC, almost any decent, proven steel except for 1095 is preferable. Makes it "feel" more custom to me. Kinda more "special." I'd likely buy it no matter what it was made out of though.
