12C27, S30V, VG10, 3G, ZDP189, 440C, ATS34/154CM.
Those are steels that i`ve got experience with anyway, best for bushcraft?
I`d recommend something in the softer scale of these, like 12C27, or 440C. This will ease the sharpening.
Harder steels, meaning that they should hold their edge for a longer period of use, VG10, is pretty good, while still not too hard to sharpen.
Steels like S30V, ATS34/154CM, are also pretty good, but may be prone to chipping, depending on how refined/polished your edge is, and what geometry it has. Also, may be harder to sharpen.
3G and ZDP189, are even harder still. This means that they hold their edge for a very long time, but are relatively hard to sharpen. May also be prone to chipping, if the edge is too thin, or not refined/polished enough.
Also, ofcourse, it depends on what you`re going to do with your knife.
Battoning, whittling, food prep, chopping, splitting, butchering.
The use will be important to take into consideration, as it will dictate thickness and angle of edge, which again can have an impact on what steel you`d want in a knife.
I hope i didn`t throw too many wrenches into the cogs, cause i sure find it difficult to recommend any steel, for any specific task, as there are so many things that count in, other than the steel.
