Another vote for AEB-L. The first knife I made with this steel was a gut hook knife for myself. I heat treated it using Devin Thomas' double quench method and dry ice. I have since gone to using liquid nitrogen.
I used it to skin, gut and de-bone my buck last year. I then sliced 39 lbs of jerky and cut up 43 lbs of meat for summer sausage and never had to sharpen the knife. About a month later we butchered and cut up 3 hogs. During the middle of the hogs, I used a diamond steel to touch it up, 3 swipes on each side and when finished cutting them up, it would still shave hair on my arm. I don't know that I can ask much more from a steel.
