I haven't used it, but it is somewhat similar to several other knife steels. Here is a comparison graph of k340, S35VN, D-2, and 3V.

It has extra chromium to give it some corrosion resistance. A tad of vanadium and a good amount of molybdenum make it form fine grain and be deep hardening.
There is just enough excess carbon past the eutectic to make some hard carbides, but leave some free chromium. This should make for a fine cutting edge with increased toughness.

You are correct. It is in the same class of materials as PD-1 but with reduced alloying so it would be expected to have lower wear resistance with a possible increase in toughness. I don't see any similarity with s35vn.

I almost deleted the S35VN comment, sorry. It probaly was confusing.
What I was saying was that the C, Mn, and Mo are close.Ni and Si are in the same range, and S35VN has more Cr and V. S35Vn also has small amounts of W, N, No and Co.
I will remove it so as not to confuse anyone.

No worries thank you for the info. I'm no metallurgist but find metal very interesting. I was looking for a steel similiar to 3v but with less alloying which led me to k340. Seems most of it is over in Europe and I don't know what sizes it comes in. I'm more trying to find someone familiar with the steel that could make me a knife. I think it definitely has potential to be even tougher then 3v with a little less edge retention. Probably somewhere between a2 and 3v for edge holding and quite reasonable to sharpen.
