1080 or 1084 is a good affordable easy to heat treat steel, so I would recommend that. 1095 is another popular choice but it has a more complicated heat treating process and I personally believe you need cryogenic treatment to get the most out of the steel. Another good choice would be O-1, I've never used it personally but a lot of other custom makers seem to like it. If you don't plan on heat treating yourself, it can't hurt to go with an affordable stainless steel like AEB-L or a semi stainless like D2. It all depends on your resources and how you want to go a out it. If you're going to heat treat the steel yourself, I would go with 1080, if you're going to send out for heat treating, then I would go with AEB-l, both steels are suitable for almost any type of blade.
I hope this helped.
