Pmv11 sharpens nothing like a2 to me. I bought some a2 chisels a long time ago. Used them a bit but was never happy. Gave them away. At that time they felt to me like a very hard saw when you put the file to it. The edge didn't seem to hold up very well. If I knew than what I know now I could probably have done a lot better with them. Pmv11 does a lot better. It feels smoother on the stones and sharpens easily enough and holds an edge very well. This of course is just my opinion. As I said in a previous post I am not using tools as much as in the past. I can still feel the tool on the stone and in the wood tho.
