I have 3 knives with 3G/SGPS, as well as several Kershaws in the similar steel they use. In my use I have been reminded more of a powder steel BG42 than S30V performance wise. I like it, with the fairly high Rc's yet no sign of chipping, easy sharpening, and very fine edges I get with the steel. It'll never hang with the S90V's with the huge amount of vanadium carbides giving huge wear resistance S90V is known for. It does approach S30V wear resistance, but IMO takes better, and more stable edges and is easier to get those edges. As I said, it reminds me of BG42, but takes finer edges, easier comparing RC62 BG42 vs.RC62 Super Gold. I like it a lot, and love the edges I can put on it.
Kershaw used it ( Sg1 or SG2) and the edges they got with it on my Ti/JYD 2 SG2 sprint came from the factory easily able to whittle hairs. This feat isn't difficult to accomplish with this steel with DMT's and a good strop on leather with Chrome oxide/green compound.
