Yeah, I just posted that in a different thread where they are having a similar discussion, Might be worth a read.
. If you can get through it (it is quite long) you will have the info you need to make a good decision. Unfortunately there is no simple answer. It is all about tradeoffs.
Buck used to use something called 440HC and they had the heat treatment down to s science. Maybe not the best for anything, but very good for most things. If they still use it, it is still a good choice. 154CM is an oldy, but still good. Sandvik 12c27 is another good mid range steel. Stepping up you might try something in S30V. A good steel, but a bit harder to sharpen.
So read the article, do some research, and you will come up with something that fits your needs.
