I don't think it was your batch...I sharpened a BD1 LW for a friend and literally ran it through a few pieces of cardboard and that in itself killed the scary sharp edge. A M390 blade could probably do that exact process say 100 times more before seeing that sort of loss in sharp. I think a Delica I have in AUS-6 gives more edge retention. I'm not sure what Spyderco was thinking there given their base VG-10 is a great steel as-is (as was their 154 when they used it.)
And I'm with you on S30V. While not a terrible steel, it never quite lived up to what was claimed of it and so it raises the question if price is justified. Most S30V knives I have are good, but no better than CPM-154 and so it's made me question if a price difference is justifiable. Kershaw has seemed to recently shift a lot of knives from S30V to their Sandvik steels which I think some give almost as good performance and at a very reduced price.
It seems steels like ELMAX, CTS-XHP, and S35VN are the steels that S30V was claimed to be. And while a lot of people say S35VN is not that different from S30V, I think the bump in toughness allows S35VN to see hardness levels that S30V would be more prone to issues with chipping/other damage, so to me S35VN is a nice improvement and more justifiable in price than S30.
I've only been EDCing a M390 knife for a short while, but I too am really impressed by performance, and was surprised how much easier it was to sharpen over other steels that give it's sort of retention/wear resistance. It's definitely a great steel for folders!
VG-10 will only be seen on Japanese knives. The Manix is made in Golden. 154CM is pretty similar to BD-1 and VG-10. The reason BD-1 was chosen was it's ability to take a very fine edge and take it easily. The other reason was the fact that it is actually one of the most corrosion resistant steels on the market. I didn't jump on the original LW because of BD-1, but was all over S110V and am really liking it.
Kershaw did not switch from S30V to 14C28N. They were using 13C26, and upgraded across the board to 14C28N, and occasionally "upgrade" a knife with S30V and very rarely they actually had some ZDP-189. 14C28N is an exclusive to Kershaw steel. You won't see it with any other knife. Now ZT is using ELMAX and M390 as their upgrade, with S30V being used quite a bit as the standard. I think the 0200 still uses 154CM as its base steel. In terms of abrasive edge retention, S30V is quite a bit better than the Sandvik steels, VG-10, and BD-1. Take that for what it is, an isolated test looking at one performance criteria of a knife. I personally do not have and BD-1, but would take VG-10 and probably 14C28N over S30V due to S30V's lower edge stability in my experience.
