Phil Wilson at Seamount Knifeworks has written a group of excellent articles covering many of the CPM "Super Steels" used by various makers in blade production. He goes into the advantages and disadvantages/difficulties of different types, and all of the writings are easily understandable even for the novice. Great material to study up on and learn that can be a great advantage in this hobby of ours.
