Get the one your maker has the most experience with and can heat treat the best.
So I'm having a custom made, and I'm having a hard time choosing the steel! It's going to be an all around, hunting blade, main uses are skinning, butchering animals, chopping wood, general camp chores, battoning wood for fires. The steel choices I'm going with, are 52100, A2, 80crv2, and possibly o1.
I'm leaning more towards 52100. Anyone have any experience with this steel in a skinning knife? Wondering how the edge retention is with a good heat treat?
